Chrysler Repair: 03 Sebring: blower motor only runs high speed, blower motor resistor, fan speed control

Question
Hello, my 2003 Sebring,4cyl fan speed control on dash will only work on high speed setting. Problem?., and how do I safely remove the plastic switch panel on dash?

Hi JW,
I am in a close race for 'expert of the month' recognition and I need to ask your help again. As with your other question, if you again would be so kind as to click on the 'Thank/rate' button below and then at the rating page click on "Yes" for a nomination of me, that would be very helpful at this time. The deadline to do it is Thursday at 4 pm. I'm up against a Microsoft 'coder' who is adept at manipulating the game, so we 'grease monkeys' have to stand together!

PS By the way the rules are that each answer is a basis for a nomination so it is perfectly acceptable for you to nominate me again.




Hi JW,
The problem is not the switch but rather the 'blower motor resistor block' that provides the various voltages for the different blower speeds. It is located in the heater/ac housing under the dash, on the underside. Locate the blower motor (by sound) and follow its twisted wires to find the resistor block. Remove its connector, then remove the 2 screws that hold it to the duct and it will drop out. Put in a replacement resistor block. You will find it easier to see what is going on if you remove the underpanel silencer on the right side that otherwise blocks the view.
The symptom you describe is virtually diagnostic for that being your problem.
