The Climate switch on this model is a "Resitor Switch" which means the full voltage is setting 4 ... 1-3 reduces the voltage making the blower motor go slower... This seems to be a common problem and the only fix is to rplace the switch... However the run around 125.00... Even though this seems to be a reoccuring problem Dodge does nothing about it except sell you a new switch.... 53K Miles on my 2002 and I am into my 3rd switch now... Don't bother changing the resistor switch because you will rack up too much money in replacing it every 2 months....I have replaced mine 3 x's now at $22.20 a peice from the dealership. The mechanics at Dodge know that this a problem with Stratus' and will tell you to replace the blower and switch, which in time, you will go through this whole process all over again. Chrysler is well aware of the problem and is not willing to do anything about it because of people like us replacing the part a million times & they continue to make money on it. Live with the fact of having heat and a/c on high for the duration of owning this vehichle!
either the blower control switch or the blower motoer needs replacing
The problem is either the blower motor resistor or the blower speed selector switch.
Blower motor resistor is bad. It is a little circuit board with resistors on it that changes voltage to the blower motor. When it goes bad, you get full speed only.
I had the exact same problem with a 1999 Dodge Stratus. I replaced the blower motor resistor twice only to find out that the blower motor itself was the problem. I know others with the same type of car, i.e. Dodge Stratus that had this problem. It turns out that Chrysler must have gotten a bad batch of blower motors form some supplier. I went to the junk yard and got another used blower motor and put that in with another resistor (the second one blew out again) and it worked fine!
Blower switch and connection had a melt down.
Sounds like the wire that goes to the blower that is behind the glove box which you would have to remove then pull the wire off and push back on, that's usually the problem.
The blower resistor has probably failed. The connecter also likes to fail. They are located under the hood on the large black plastic housing on the passenger side. There are 4 wires in the connecter.
i think it probably because the motor has a ground problem or it has bad brushes and is is drawing to much energy for the resistor
replace the blower motor switch
It is the blower resistor. It happened to mine and from what I can tell it is a common problem. Here is a site that helped me it also shows you how to replace it. You can find the part at AM Auto parts. http://www.sparkys-answers.com/2009/01/2002-gmc-envoy-no-low-blower-speeds.html
blower motor resistor is burned out
This is not a complete answer ,butl go to auto zone.com they do.
