Yeah I know my thread's a bit old, but I never got around to fixing the air flow ****, (off, 1, 2, 3, 4), that only works on 4 or Hi. So I went to Napa today & asked for a blower motor relay & told him it only works on hi & he said its not the relay, its the blower motor resistor & the darn things $50 bucks! I wasn't in full agreement nor did I have the $50, so is there a way to figure this out with a multi meter before I go spend $50 smackers???
Oh & both the resistor & relay are directly behind the glove compartment in my 98 Limited & u only need to remove the rubber stoppers to let the glove compartment swing all the way down & there they are staring right at you.
((I tried an off the shelf relay that matched up & nothing worked with that in. I priced the relay at Napa & even that's an $18 buck gamble!))

You can access the resistor by removing the kick cover under the glove box. 4 fasteners. For the top 2, the cover is slotted so you don't have to completely remove the screws.
Remove the resistor and eyeball it. You'll probably find it is cooked. Check the connector as well.
If you have an Advance Auto Parts near you you can order it on line and apply their discount code and get the resistor block for around $38.

Thanks for the info!
Has anyone on here used this $2 buck resistor from Radio Shack seen in this thread: http://www.jeepforum.com/forum/f11/b...sistor-206575/ ??

Several times on my '93.
That is a thermal fuse, not a resistor. Should be available at Radio Shack (assuming they are still in business by the time you get there)
If it blows again you will probably have to replace the blower motor but let us know
Edit: I didn't read the whole article but it is best to use some kind of simple heat sink when soldering the fuse in -- anything you can clip on the leads.
