compressor is working and the blender motor is working. I am guessing that one of the hot or cold blend doors is partially broken. It does go hotter to warm. Not cool/cold temperature wise. Is there a quick fix until I can rip my whole dash apart if need be???
Hopefully???

It does not. I forgot all about that being separate. What all does that cause? Other than high head pressure at slow speed?
No heat transfer.

If the AC works while your driving and then fades away when you come to a stop, the condenser fan is the culprit.
The fan should run anytime the AC is on(usually at a slow speed).

Well. I better check to see if the fan motor is good.

See if it's running, if not disconnect the connector and see if you have power to it. If you do then it's the fan motor. If you don't then it's another issue. Regardless, take it for a spin with the A/C system on and get up to highway speed, see if it cools off (this verifies the rest of the system is good).

Well, seeing some weird things.... while monkeying around with it I found the clutch is weak and has now completely shorted out. Zero resistance. I think it may not have been completely engaging when called on. Computer thinks it’s on. The TIPM is completely solid state and seems to have some weird over amperage safety switching capabilities. Not sure that this is also shutting down the fan. I will function test it independently.

So, this was a fiasco. The armature on the compressor clutch was shorted. Of course the parts stores don’t sell these anymore, for this vehicle at least. So I had to buy a compressor with a clutch $300. To top it off, in order to get warranty I had to purchase an orafice tube and drier too for the compressor I did not need.
I wasn’t sure whether the fan would magically/electronically start functioning or not when the ac started working. It didn’t. Replaced that too. AC works great now. What a great luxury.

They tend to require those for warranty when you buy a compressor because most people get one because theirs went bad and depending on how it went bad, it may spread debris throughout the system. Glad to see you got it fixed and thanks for posting your solution/resolution. Most people don't.
