is it the switch???

so i went to the dealer today to pick up a blower motor switch because my blower was only working on speed one. the parts guy said its probally my resistor and not the switch. so i got the resistor instead and put it in. pulling out my old one i saw it was all rusted and cruddy looking so i figured that was the problem. the wires on the plug all looked ok to me. tested it out and still no other speeds but one and now the air only comes out of the defroster. what should i do or check??

Try replacing the switch. I had the same problem when I first got my jeep. Pulled out the switch/knob assembly and cleaned all the contacts. Works fine ever since, but it was a PITA to reassemble. Next time I'll just buy a new switch.

Air coming out of defroster is often a vacuum leak from the manifold. You can order an entire switch panel from chryslerpartsdirect.com cheaper than your local dealer.

My blower switch melted entirely making it necessary to replace the set. There are several good write ups on here, search "blower motor" or "blower switch".

Switch is easy to check with an ohm meter. Just a 4 position switch meaning 1 line in and 4 out.

The more of these you have... the easier it is to get over obstacles in your path.

ended up being the switch. the parts guy was cool and gave me wholesale cost on the new switch because i listened to him and had to spend 47$ on the resistor the first time which i didnt need, but probally would have down the road.

I'm glad he gave you a deal since he gave you the wrong info to begin with. I'm sure he probably didn't know better, but for future reference a faulty resistor will not affect the highest speed setting.

Yeah I knew that it would work only on hi going in there if it was the resistor. He told me in his '03 he replaced 3 resistors already and really thought that was the problem. But its fixed and hopefully i wont have to go to the dealer for dealer parts any time soon.

I also had the blower stop working in my 98 TJ w/AC. I purchased a 05011214aa switch from the dealer (who wanted to sell me the entire unit). It doesn't quite fit. The holes are wrong and the speeds are medium high low and very high as you click through the speeds. The post is too thin for the knob as well. It is working though. Does anyone have a different part number for the switch I need?
