I have a 98 chevy blazer with what i thought was low freon initially. this was my assumption at first because the compressor was starting and stopping right away. Once freon was added, the compressor problem resolved, however, the air in the car still blows a slight form of cold.

I have tried freon with stop leak as well as just with dye. From what i can see there appears to be no leaks in the coolant lines. The lines themselves get very cold and sweat does appear on them. From what I can see it appears the system is working correctly, just not making into the cabin of the car. Does anyone have any ideas what might be causing this problem?

 

Hello,
Use the search feature of this forum and look up Blend door actuator. Seems to be a somewhat common issue. Let us know what you find out.

 

Thanks for the tip. I think that is the problem. I already got the part out, closed the door all the way manually and seems a bit better. I'm just waiting to receive the part in the mail.
