Re: 98 chevy blazer with AC problem after freon charge
Automatic Climate Control or manual AC?
Can you vary the temperature of the air comming out by adjusting the temperature knob? It's possible the actuator is at fault but, make sure the refrigerant system is working properly first...
The HT6 compressor has a habit of leaking where the case is bolted together. Usually on the bottom side toward the center of the compressor, and it's usually caused by improper installation. If you have UV dye in the system, you should be able to spot the leak with a black light and a small mirror.
Clutch cycling systems will not operate properly with too much or too little refrigerant. As little as 2 ounces plus or minus can make a big difference. The ONLY way to know how much refrigerant is in the system is to drain and evacuate it to 29"Hg for a minimum of 1 hour, then charge with 30 ounces of R134a. <<<1998 factory spec.
