my 2003 Impala vibrates very bad, but only when I accelerate. when i let off…
The blower motor in my 2008 Chevy impala 3.5 engine cuts out completely. A few swift kicks under the glove box usually gets it going again. There are no strange noises,
all speeds work, and the temperature adjusts as it should.
- Check the connections at the blower motor
- Confirm battery negative and positive when the blower is not working
- Replace blower motor
The kicking under the dash is probably enough to jar the internal brushes in the motor just enough to get it to make sufficient contact. This allows the motor to operate until the next time. Replacing the blower motor would be the fix.
