I thought I posted this here, but I guess not.. anyhow..

On my climate controls, my lowest fan setting doesn't initiate any fan speed anymore. We typically like to keep the fan on the lowest setting too.

I'm thinking the contacts have corroded or fouled, any issues with spraying some contact cleaner in there to try and tidy things up a bit?

Are these things expensvie to replace? Whats typical shop time for a part like this?

 

It's probably the resistor, or a resistor pack in most vehicles. I've never worked on it on the Ram but that'll give you something to search so you can find its location and replacement info pretty quickly.

 

sounds like the Blower Motor Resistor. about $50 online at rockauto.

 

Would that only affect one fan speed?

 

Yes. Each fan speed results from the current being fed through a different resistor. High speed = no resistance at all, which is why it almost never fails. When you lose a resistor, you lose its corresponding speed.

 

Excellent..

Thanks for the help.. I was thinking this was a dealer's job, but after looking at the instructions, it seems fairly simple.. I think I might tackle this myself!

 

All you need is a phillips head screwdriver, I did it in the parking lot of the parts store when mine quit working.

 

i had a similar problem with mine, i took the blower motor off and cleaned it out, and all is working now

 

Do it ur self cause u would probably get charged 100 bucks to install a anew one. it'll only take about 20 mins. i think its behind the glove box. but it really sounds like the blower motor resistor to me.

 

can someone give me a link to instructions on how to replace the resistor? I have a 2002 Dodge Ram 1500 4.7 ltr Quad Cab
