The blower on my 2003 SLT stopped working again.

Bought the truck in July 2010 and replaced the resistor to make the blower work again. In September, I replaced the resistor (2nd time) and bought the harness kit and wired it in as the resistor melted the old harness this time. Everything worked great until last week. Blower stopped working completely.

New harness looks fine. I can replace the resistor again but what could be causing it to fry this often? Could the blower motor be just worn out and drawing too much current through the resistor block?

Thanks.

 

Ask if you are getting a newly redesigned resistor or one of the older original resistors still located at the parts warehouse.

Got it from Napa today. It looks the same as the last one I got and they verified it is the newest design. Any ideas?

 

sounds to me like there is a short in the system somewhere (probalby in the fan) that needs to be tracked down and taken care of

 

+1 Indy....check the date of manufacturer. Probably one of the few times I would consider dealer.....due to high fail rate they are usually in stock at dealers and you can check date of manufacture. They are reasonably priced and based on the fail rate it probably wouldnt hurt to have a spare on hand...

When you do get the short solved keep your bad resistor for troubleshooting especially if you have to do some wire splicing..... no sense in installing and burning up a brand new resistor. Once you have the final repair done then install the dealer resistor.

 

I have the same problem...i replaced my resistor during the end of the summer and a few days a go my blower stop blowing unless wiggled the resistor...so i unplugged the harness and found it is burnt inside the plug as well and the resistor connection is burnt....the dealer told me the blower is bad causing a high current draw which burnt the harness and resistor....my question is... shouldnt it blow a fuse to prevent it from burning more and causing a fire because it still works sometimes?
