2002 Stratus A/C knob problem
I own a 2002 stratus w/ 38000 miles on it. Today i had my AC on setting 3
and the blower was working fine. I turned the car off. ten minutes later turned the car back on and fan settings 1-3 wont work at all. Setting 4 works fine. I checked the fuse, and it was fine. all other accessories are also working. I was poking around under the hood, and pulled out the Rad. Fan Lo relay(with the car off) then replaced it, and since i did that the Check engine light is on. any tricks to turn it off? I know its only on cause i pulled the relay. Any help or ideas would be much appreciated. Thanx, -- Matt C. Philly, Pa |

OK-- so i have done a lot of searching since i posted this, and i found out
that alot of 90's model dodge trucks had problems with the blower resistor pack on the firewall. Can anyone tell me does my dodge have this same resistor pack/possible culprit? and if so, how do I locate it? Thanx -- Matt C.

In the process they heat and can burn up. Usually the assembly is screwed over a hole in the firewall so the resistors themselves are in the air stream from the cowl air intake, to cool them. On some vehicles the assembly is screwed to a hole in the heater/AC housing, still in the airstream for cooling. Another possible fault, if it exists on your truck, is a diode that is connected in the same circuit. It is meant to "brake" the fan when you switch it to a slower speed, so it slows down quickly instead of freewheeling down to speed. If it fails, it usually results in one fan speed only: high. If your vehicle is so equipped, it's part of the blower resistor pack. It can fail without the resistors going bad; last one I saw was on a 92 Dakota, and we simply clipped it out. Maybe the fan freewheels a bit more when it is switched from HIGH to a lower speed, but it's not as though we noticed. |
