front blower motor problem on 2001 dodge Caravan Sport
I have a on going problem with the front blower motor on my van. Sometimes the front blower will run and sometimes it won't. The rear blower works fine. I have replaced the fan resistor behind the glove box and it did not solve the problem. I would appreciate any help and advice on how to troubleshoot this problem.

It's either a bad motor or a bad connection on the switch/relay. Look for discoloured connectons - not as common on Chrysler as on Ford. As for the motor, often the brushes are worn and/or stuck. Replacement is the best bet - but if installing used stuff, for crying out loud make sure it's in better shape than what you are taking out!!!!. For the work involved, it does NOT make sense to install something that is already worn out. |

Hey, I KNOW they are easy - Which is what I meant by make sure it is in better shape than what you took out and replacement (of the brushes) is the best bet. Sadly, replacing the brushes doesn't always fix them when they get to the point they don't run any more, because the commutator gets worn /burned/ gouged to the point it cannot be readilly cleaned up. Then a good used one (check and replace brushes if necessary) or a new one is required. When having a used unit installed by a scrap yard you want to make sure they warrantee both the part and the labour - and they have actually checked the part before installing. The good ones do - but MANY do not. The labour, generally, is worth more than the (used) part. |
