I don't know if your setup is different than my 2002, but when mine went out I located the connectors going to the heater at the firewall and was able to disconnect the in and out hoses and join them right there using only a screwdriver if I remember right.? Took 10 minutes at a rest area and we finished our summer trip without heat.? No problem.?
Pulling the dash later to change it was a pain, though.??
