2005 SLE AC Issue
Symptoms: Occasionally the blower does not kick on. One time I powered the AC off and back on which fixed it. Other times nothing will fix it. Just one time the system wouldn't push cold air like the Freon was low. Now that everything is working right, it is in the shop (GM dealer) where they won't be able to do anything.
1. Who is right? My regular mechanic (used to work at a Ford garage) said it needed to be hooked up to the computer to see if the system detects any codes that might point to the problem. Dude at the GM garage doesn't want to do that because he says the AC system isn't connected to the computer system.
2. (Assuming my regular mechanic is right) Until the AC system reproduces the symptoms, the computer won't throw codes anyway, right? So running computer diagnostics will only cost money for no results?
3. Anyone have an idea what might be the cause of this issue?
