I have a 1994 Brave. WF-31RQ. When I turn the heat or AC on, the blower blows for about 5 minutes and then shuts off. If I turn the blower off and wait for a little bit (3-5 min), the blower works again. when this happens, I have no voltage at the blower.
It almost seems like a circuit breaker is tripping and then resetting. I can't identify where this would be. Could the relay
be bad? Any ideas?
Please note: my blower motor is new -- I thought maybe there was some sort of thermal shutoff in it and I replaced it. My blower motor resistors seem are fine...and they only affect lower speeds -- I believe they're bypassed on high. I also had deteriorating vacuum lines from my vacuum reservoir (ball) to the vacuum source on the manifold that was causing most air to go to defrost (and a little to go to heat), but I got that fixed.
