Dave,

The Bentley wiring diagrams for a 2003 show the following devices:

G2 (sensor for temp. gauge) and G62 (sensor for ECU) combined in a
4-pin device and mounted in the thermostat housing. This is the
upgraded green D-shaped device (originally black).

F163 (A/C cutout thermal switch) and F165 (3rd speed coolant fan
control thermal switch) combined in a 4-pin device and mounted in the
thermostat housing. This is the green square device.

F95 (after-run coolant pump thermal switch). The Bentley doesn't show
a location for this device.

On models WITH Climatronic (i.e., GLS and non-Weekender MV's), F95 is
shown combined with G110 (A/C engine coolant temperature sensor) into
a 4-pin device. G110 is shown in a location "behind intake manifold,
center, in coolant hose above exhaust manifold heat shield". But
maybe this device is really mounted in the thermostat housing? And
maybe the 4-pin device is installed in vehicles which aren't outfitted
Climatronic, even though one half of the device isn't actually used?
The Bentley CD isn't very helpful here.

And finally, there's FC (coolant fan control), which is a 3-pin device
shown mounted near or in the radiator and not really part of this
listing of devices in the thermostat housing, but I thought I'd list
it since it is related to coolant temperatures.

I have a 2003 Weekender. Next time I pull the belly pan, I'll have a
look at the thermostat housing to see what's there. I did replace the
black with a green D-shaped device several years ago as a preventative
measure.

There is something wrong with this "good info" because it describes
all 3 sensors as 4-pin sensors, which would mean 12 pins total, and
that would mean 6 devices.

But, as far as I can tell (I have a '99 12 valve, and a paper Bentley,
but there has been a discussion on vortex -- complete with wiring
diagrams posted for the 24 valve motor -- and what I've seen is
consistent with mine) there are just 5 devices:

ECU
gage
fan
afterrun pump
AC cutout

Various models -- the 5 cylinder, the 12 valve, the 24 valve -- have
various locations and combinations for all the sensors involved (for
example on some models the ECU and gage sensors are combined in a
4-pin device while on other models the ECU sensor is a 2-pin
device) but all models use only those 5 devices, which would mean only
10 total pins.

But, Dave's information shows 3 devices with 4 pins each which is 12
pins which means 6 devices.

Something is not adding up. Does the 24 valve motor have a 6th
device? If so, what is it?

Good info.

And when replacing the sensor, if you replace the cap on the coolant
reservoir (after relieving any residual pressure), the amount of

coolant loss will

be less that a cup.

And the new green d-shaped (oval) sensor did the trick.

The dash gauge is now working.

Another note, I think the AC was not working while this sensor was
malfunctioning. It seems to be working now. I'm not sure if this is
related.

So to sum up ...

There are two sensors under the engine in the thermostat housing.
You'll have to drop the belly pan to get to these, they are on the
driver's side.

The 4-pin d-shaped (oval) is for the dash gauge and the fuel
injection. The new sensor is green, the original one was black. the
black ones are a known problem.

The 4-pin square sensor next to the d-shaped sensor is for the fans.

There is a 4-pin blue sensor in a hose near the top of the block that
is for the after-run pumps.

Each sensor is held in with a c-clip. Each sensor has a rubber

o-ring.

It is possible to swap out the sensors without draining the coolant
system, but you need to be quick with the lower ones (make sure the
coolant is cold, safety goggles and a closed mouth are advised)

The o-ring does not always come out when you pull the sensor. Make
sure it is accounted for before replacing the c-clip. Also be sure
the sensor is under the c-clip not over it, or it will pop out and
drain all your coolant.

Sensors and o-rings are available from Steve at

Bruce: How do you vacuum the vent?

Karen

-Bruce- I did the vent vacuum trick...thanks for bringing it up. This
fridge has always worked super on gas and I just want to keep it that
way.
When I pull it out, I'll be able to look closely at the burner box
and scope out this visual inspection issue.

The bit of fluid that doesn't
come out in a change is likely to be uber-dirt-concentrate

The bit of fluid? LOL

Well over a third of the fluid won't drain out the pan. Have the
transmission flushed, period.

It's not the dirt, it's the FLUID. The fluid has worn out. Viscosity
break down. Thermal damage.

Hasn't this been discussed a thousand times? Change the fluid. ALL
of it.

Make sure the pan is clean and also do the trans pressure screw mod

as well while you're in there.

Being that you went to over 100K with the original fluid, you might

even want to do two fluid

changes (do once, drive around for a while, maybe until next

weekend, then change it again...or at

least do the next one after about 10K miles to get all caught up.

I don't think I can do this ATF change myself so I was planning on
taking it to AAMCO or Lee Myles and asking for them to flush and change
the fluid. I remember talk of a screw that can be adjusted, but I
forget the details. Can I trust Lee Myles with this king of power?

TED,
My 2002 MV EV transmission failed at 70K miles. It did hesitate and
slip a bit especially going up hills. It never made much noise
before going out, and was never difficult to put into gear. I think
that reverse was tough thou sometimes.

Catch now if you can. Apparently mine failed because the
tranmission fluid got burnt at some point. I was really pissed
especially since it was just a few thousand miles out of warranty.
It cost closet to $10K to get replaced and VW only gave me something
like $600 assistance.

Greetings friends,

If you have already experienced a failed transmission on your
Eurovan, what were the first few signs of failure?

Hesitating once in gear....like when you accelerate from a red

light?

The transmission won't go into gear?

It slips a little here and there as you are going down the road
(feeling bad)?

When you first get into the car and put it in Drive (or Reverse) it
won't catch for a few seconds?


Thanks for you input. I just want to know what to watch out for!

I was running some errands yesterday, my MV was starting fine, no
hesitation whatsoever with when starting. I make a quick stop, get
back in to leave and the car will not start. Plenty of power in the
system, just nothing getting to the starter. It's as if the starter
just got unplugged or something. I looked around for a blown fuse but
found none.

What could it be? Anyone had a similar problem?

Thanks,
Philip

I noticed that you have recommended doing this mod numerous times. How long
ago did you do the mod and what are the results?

Bob W.

You don't need to remove the panel--there are a couple of screws under the
fridge and two (I think) on each side. Remove the screws outside at the vent
and you should be able to slide it out. As soon as you get it out a couple
of inches the propane line -12 volt and 110 connections need to be
disconnected. Make sure that the gas is tuned off before you do anything.
Take apart the burner box and check the thermocoupler and makesure the
burner is clean and all of the slots are open--if there is carbon buildup
use soap and water to clean it out --brush the inside of the flue out and
you should be good to go.
Take your time and it will only take a few hours . Good Luck

Hi everyone,
I've a 95 EVC and would like to take out the refrigerator to check it
out (it doesn't work now) Is it hard to take it out, and then, to put
it back in place? How to I disconnect the refrigerator exhaust ? Also,
do I have to remove the control panel above the refrigerator ? What
else should I know ?
Thanks to all.
Felix A.

Could be you only have a problem when the fluid is still cold. It
might be dirty (likely with 102K) or the level might be a little low.
I would just do the normal drop and drain ATF replacement, along with
a new filter, and see if behavior changes.

I don't think you need to go into panic mode yet!

Carl

If the thermostat is bad, you can verify by jumpering the 2 wires
together which will call for heat ll the time. If the furnace burns OK
it's the thermostat.

It would be interesting to modify the furnace so the fan runs all the
time (perhaps at reduced voltage to conserve battery and generate less
noise). That way it wouldn't wake up light sleepers as it cycles on
and off. Would probably have to verify that such a modification was OK
with the furnace people.

David,

I'm no expert, but when my window stopped working and someone here told
me that a wire was broken between the door and the main part of the
car, I thought that they were grasping at straws, but they were right.
Peel back the rubber boot in which the wires run between the car and
the door. Feel along the wrapped wires and maybe you will feel a
break...if not, unwrap the wires and look.

Good luck,

Ted

Hello Gang,

Is this a death sentence? I shift into Reverse to back out of the
driveway and there is a 2-5 second hesitation before it slips into
gear. I then shift into Drive and everything is fine. There are no

PS -

On my 95, there was several l.e.d. indicator lights on the circuit
board and a sticker to explain their function. That might be of help.
If you can't find the sticker:

green=start cycle
red=valve open
slow green=bad electrode
fast greeen= timed out

I ended up cutting a hole in the forward side of the shroud and
copying the sticker and pasting it where I could read it with the
furnace intstalled. Now with a mirror I can troubleshoot it while it
is installed (after removing the gray plastic interior panel).

The Eurovan service training manual from Winnebago (I bought mine
from Go Westy), has 18 pages on the furnace.....troubleshooting,
wiring diagram, etc. You might want to pick one up. It covers
everything Winnebago added to the van, in detail for servicing.

Both my mirrors stopped working today. If I press up or down, I hear a "clunk" from both
mirrors but no movement. If I select right or left, no sound or movement. Wish I had a
schematic.
