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.

Jimmy 2000 Heater Blower Not Working by mkcurare

My 2000 Jimmy stopped blowing air. I have heat and defrost, just no air movement. I'm not sure where the blower motor or blower motor resistor are located. On this model they seem to be hidden by a sealed black plastic shroud that must be cut open. Is the motor resistor located within that black plastic shroud or is it mounted somewhere on the firewall?
 
Thanks in advance.

My 2001 Blazer just suffered the same fate. How do we get to the fan motor?

Resistor is under that plastic cover - cut to access. The fab motor is accessed underhood on pass side.
