The fan switch control for the AC/Heater comes on like clockwork about 20 - 30 minutes after driving the car. I have manual temperature controls and replaced the fan switch control assembly with no luck, the heater fan motor will start after only 15 minutes of driving, sometimes right away. It will run for hours once started and sounds perfect, but if I stop the car for an errand leaving it off for 15 - 20 minutes, it will take 15 - 20 minutes for it to come back on. During the summertime, it is the same pattern with the AC - it will take 5 - 10 minutes for the AC to come on, but winter time seems to take much longer. Please advise. Thanks!
