98 Jimmy Stange A/C problem by e5husmc

Last spring the A/C was only putting out a little cool air so I bought a can of R134 w/leak detector and everything was fine. This fall after using the heater for a couple of weeks the weather got warm again, A/C isn't cold again. Put in another can of R134 w/leak detector, cleaned around hose connections and compressor, no leaks found. Stayed cool until we used the heater again. Anyone have any ideas?

How do you remove the evaporator in a 97 Jimmy. One of the bolts is inside the passenger fender and looks almost impossible to reach. Dealer wants over $1000 to replace. Many thanks.

Air Door Actuator by vicedetective

Hello all, okay I have a 96 GMC Jimmy with just the normal climate control. Just the red and blue for hot and cold type. I was having a problem with getting any real cold air from the A/C and was told that it was the air door acutator. I bought the part, its a small part. What is the best way to attack this project. First do I have to remove the dash 100%, and where is this part exactly. I have read some say yes on the days others say no just get behind the glove box, but the glove box is attached to the dashboard or am I missing something here. I took the glove box door off to see. Please help, I have a little one on the way and live in the dessert so I need the AC in the wifes truck, thanks!

1995 GMC Jimmy: Heater Fan stopped blowing by bg3000

When I started my '95 Jimmy yesterday morning the heater fan was on and blowing, so I turned it off until the car could warm up. When I went to turn it on again the fan didn't come back on. No noise, no fan , no nothing. I checked the heater fuse and replaced it, but no luck. Any ideas?

Probably the fan motor died - cheap part to replace from underhood and believe only 3 small bolts - all stores sell them. Also possible fan resistor mounted by AC box but thats speed control so fan should still be on at some speed.
