200 Chevy S10 Blazer A/C Problem

[mustang_guy3]

Okay I am having a problem with my A/C in my Blazer I've had my compressor replaced finally got all of my leaks fixed and replaced all the visible vaccum hoses and still without by passing my heater core I have no Air Conditioning. It just keeps blowing out hot air. No one seems to know or have any idea as to why my Air Conditioner is working. I really like my blazer but after having invested a little over 600.00 into just getting the A/C up and going with no luck is just getting frustrating. I am considering selling it and getting a truck. I would like to keep it if I can get the A/C up and going but I don't want to have to invest a whole lot more money into it. If anyone can help it would be much appreciated.

Do you have manual system? or climate control? Sounds like your temp door is dangling loose- or a bad temp door actuator. You can pull off actuator- it's tight but do-able. It is on top of HVAC case- open glove box and drop it down- then work to get the screws out of temp door actuator- once it is out, you can see if it reacts to control head temp commands- and you can also move temp door with your fingers to full cold and full hot- and see it your system works then.

I suspect you have a broken drive gear internal to the actuator- which requires a new actuator- if it does not move in above test- there-in is your problem.
