The ACC fired right up this morning (80+) - and worked all the way to work. This evening, (98F), I could feel the compressor running, and feel cool air coming from the appropriate vents, at 70 MPH with the windows cracked, but the fan didn't come on for the first 10 miles or so. Then it suddenly turned on. I didn't loose cooling at all.
So - I have sporatic random failures of different parts of the system. I did re-solder all the joints in the push button unit last summer, but I'm not discounting failure in it. Is the pushbutton unit, the control unit, or something else the most likely suspect???
