Guys, thanks for your help and links to show me how to change out the blower motor resistor. Here is my new issue.....I got the resistor, from a Chrysler dealer on Ebay $25. I pulled and unlocked the red tab and went to pull out the old resistor, it was stuck, I didn't realize until after that there was also a little black tab in the same area as the red lock tab that needed to be depressed. When I went to pull the reisistor out of the hole, I bent it and the thin, wafter like end on it broke off and fell into the air duct. The hole is so small I couldn't fetch it. My question is, will leaving that broken piece inside the duct harm anything? I put all back together, put the negative cable back on the battery, and the blower now works on all levels with the new part. Any thoughts on the broken piece would be much appreciated!! I have been driving it all week with heat on (getting cold here in Canada) and no issues. I just want to know if this is safe just leaving that broken wafer/chip piece in there.... Thanks.
