1994 Caravan Heater - How hot is yours?

Oops!

A lot of times, it's not the A/C or heater, but the air duct doors are not coming to the proper positions to blow heat or A/C air into the cabin. Do a web search for "Caravan" "Heater, A/C calibration". It involves holding certain buttons down for a few seconds. That resets the vacuum doors to the original factory settings. Worked like a champ for my van.

Make sure your coolant level is correct.

Otherwise, there was a Tech Service Bulletin covering blend door sticking.

Older technology for an older van.

Following the procedure here:

Thanks for the suggestions. Lots of heat now. I'm ready for ski season.

Great. That's just great. NOW he tells me!

Three years ago I bought a Scion tC, and had a Grand Voyager and a Chrysler LHS (GREAT car, BTW, and I am the number 1 Japanese car fan in the country!). I did a spreadsheet comparison of the work I could do, the work I would have to have someone else do, and the parts needed, and the Grand Voyager won by about $1,000, so I traded the LHS for $600 towards the Scion (still makes me sick to think about it...).

I had the same heat problem, and in trying to remove the water pump I broke the idler pully bolt off in the block. Hey! I TURNED it the way they said to!

No problem with the water pump, except I broke 6 of the 10 bolts holding it in. I gave the van away. Then I heard about the blend door...

That's OK. I pick up a '92 Grand Caravan tomorrow...
