air conditioning compressor turns on, when climate control button is pushed, blower motor does not turn on. checked under dash to see if power is being sent to the blower motor, when compressor is turned on. no power at blower motor. apply power directly to blower motor and it turns on. changed push button control units with a friends '89 420SEl that works properly in his car and still no power to my blower motor. any ideas as to what else to check?
