Q: I'm having issues with AC blower controls flap will go from face to feet after a few minutes then comes back randomly

asked by on

I recently found out I had a leak on AC compressor and had it replaced at a shop. I have had issues with my AC button on my AC Heater control switch. I would push the AC switch and start driving down the road then it would would randomly turn off by itself. I looked up online and and seems to be a common issue with several GMs around that year. I saw a video on how to fix on your own (didn't think I would be that crafty) so I bought a new AC Delco AC Heater control switch. I installed the control switch and for the first time in a long time I had continuous cold AC. But now it seems another issue has popped up. When I get into car and turn on air I always have just regular air going thru the top face vents. I hardly ever use the feet fan even in winter. The AC will be running fine then it seems the face vents go out and only can feel a lower feet vent. This isn't permanent as while driving it will switch back to face or after parking. Is this an electrical, vacuum or bad new switch?
