I have a 98 chevy truck 1500 5.0 liter. My ac works well except sometimes when turned to the highest speed it works or it doesnt. Can you help? Every other speed works fine just the highest one is 50 50.
Take out the control module and make sure there aren't any burn marks or cracks of some sort on the board. I had a similar problem and found that a new module fixed it. When i say module, i mean the switch in the interior and in the dash under the stereo. Hope that helps your problem
