Well after dealing with it for 3 years I finally fixed my intermittent a/c- heater blower. The symptom was - I would turn on the key and the blower worked, once I started the car and the blower would shut off. After driving anywhere from 2 min- 20 min the fan would just come on by itself then be fine until the key was cycled off. After 3 years it finally would only work maybe 20% of the time. ----- the fix, actually not that hard to find, ended up being a faulty "start drop out relay" located in the front relay box. It is the 5th relay from the back on the right side (gray 30a Bosch). I've just been too lazy to fix it but glad it was something simple. Mike

Usually affects the sound system too if it is that relay.

The radio is controlled by the relay directly behind the culprit. I know because I switched them to verify the repair.
