My wife has a 2002 Chrysler Sebring, 4 dr with the v-6. Just recently, her blower quit blowing on all settings but #4, the highest setting. It does this whether on; vent, defrost, floor; A/C on, A/C off; hot air, cool air.

I think it must be the switch, but could it be the blower motor itself? I would think that if a fan goes out, it wouldn't work on any speed. I want some opinions before I take it all apart this weekend. The A/C works fine when it is on, so it is not that.

 

I can't speak to that specific car but some of the older cars had a ceramic block with a resistor mounted on it located by the blower motor that was used to step down the blower motor speed. As I recall, the switch could be fine and the resistor burned out and end up with what you described. Having said that, it could be that they built both components into one unit in that car - I don't know.

 

Not sure about the blower speed control on your Sebring, but on my Lebaron (what your car replaced), it uses a resistor to control the speed of the blower. It sounds as though your resistor has blown. Especially if only High works, since High would bypass the resistor and send all available power to the blower and run it on high. Other speeds run through the resistor and limit the current going to the blower.

if the blower motor goes, it goes. I would pull out the switch and read continuity [with an ohmeter] across all contacts. setting 4 should be the only on that doesent read OL[infinite]. then it is definitly bad .good luck

 

is it off all the time except 4 or blows the same as 4?

there is a similar problem with the first generation nissan frontier. near the blower motor is a resistor board. this goes bad on our trucks and costs about $25 to replace. You might check with the service center and see if the sebring has the same resistor setup.

 

Should be a blower motor resistor in there someplace, first three speeds would run through the resistor causing the slower speeds, high speed would be the full battery voltage which may run on a seperate circuit. I think the eary escalades were like this.

 

Thanks for the input guys. That is what I was thinking (and hoping too). I'm going to pull the switch tomorrow and take a look at it. I'll let ya'll know what I find.

Cheers,
Dave

 

WE HAVE A WINNER! It is usually located in the vent air stream near the blower motor.

 

The switch is fine. It's the resistor thing. Ceramic block resistor. Go to a parts store and ask them to see a diagram of the blower motor. It is in the wiring diagram. It's about 1" x 2" and has two screws, and several wires.

Dang it I cannot remember the name of it, but it functions as a resistor at the different settings. If it is "open" (broken) the only position (on your speed switch) that will work is full blast.

 

I believe that car has the resistor in the bottom of the evap housing. Its the "credit card" style.

 

Dodgetech, I just had to say....your location description is funny....the plywood state...

 

My wife had a 2001 Stratus that did the same thing.



We traded it.
Someone elses problem now.

 

Thanks! .............
