Hi - Driving this morning the front blower fan was working fine. After turning off the car and later restarting it, the front blower fan would not work in any of the position (slow or fast). The rear blower fan works fine. Got home and took out the blower fan. Hook it up to a 12 volt source and it works. Check the fuse panel on the drive side dash and under the hood. All fused look good. Please help.
Thank you - Tony

My blower only works on the highest setting. If I turn it down, it just stops blowing. Also the back blower will not blow warm air. Is it my blower or something else?

Hello,

Sounds like your blower motor resistor. The resistor for the front blower motor is located in the engine compartment on the passenger firewall the rear is located near the rear blower motor housing.

The blower resister was replaced less than a year ago, because it stopped working, now it will only run on the high control, what is the cause of this?

The blower maybe drawing to much amperage and may need to be replaced

My blower motor in front will not work when I checked the motor direct to the battery it works. When I hook it up and checked fuses all ok both inside fuse panel and under hood fuse compartment but the blower still doesn't work. But I did notice that the rear blower has a relay marked on panel but I have not found the front relay is located

The heating in my Durango was working fine, and it suddenly stopped blowing air while I was driving. The rear heaters still blow air fine, and I can feel slight hot air when I put my hand against the vents and the defroster in the front, but there is no force. Before it stopped working, it would mostly only blow air on the highest setting. Now it doesn't blow on any setting. Is this likely a blown fuse, or is it something else? And how would I fix it?

It could be a fuse, but not in the sense you're used to. The common failure is the fan motor bearings get tight, and that makes the motor draw higher current than normal. The fuse is a thermal fuse built into the resistor assembly. Most people just replace the resistor assembly but that is going to fail again in short order. The fan motor must be replaced too.

We don't get involved with costs here because there's too many variables. You can look up the parts on any auto parts store's web site. That will give you an idea, but you'll pay more at a repair shop, just like you pay more at any other retail store.

Replacing the resistor assembly usually takes just a few minutes. The fan motor could be a simple job or very involved. I never did one on your model, but any repair shop can give you an estimate. Most of them go by a "flat rate" manual that lists labor times for each procedure. That way they all charge you for the same amount of time. Only their hourly charge will vary.

You have to remember that the cause of the problem hasn't been properly diagnosed yet. I only went by the symptoms you described. You could have a bad switch assembly too, especially if you use the heater fan on the higher speeds a lot. That increases the current flow through the switch and can easily overheat the contacts. That can result in one or multiple speeds not working at first.
