(it's shape is sort of a cross between elliptical and diamond) remove the wire clip and you see 4 metal tabs. Remove the 2 bolts and the resistor is attached to the other side of the plate. You must first remove the glove compartment to see the resistor" the info in the quoptes is for a 99 but shouldnt be too diff check the electrical conter for the blower motor resistor most of the time it gets burnt and loses contact take a look there to see if that is the cause does any speed work on the control?

I did have one that iced up one time so bad it was the fuse. Otherwise that fuse blows for a reason Link to comment Share on other sites More sharing options...

This eliminates alot of other items like the switch or resistor. I have seen alot of these problems related to leaves and pine needles getting into the evaporator case, clogging the drain, and causing ice-up issues. The water in the case, over time, will cause the resistor/diode components to corrode or loose contact. It always pays to visually inspect the resistor whether the motor is puked or not. Corrosion on the resistor can also cause intermitant issues, like hitting a pothole and it works, then cuts out. The voltmeter won't lie, I use it first, then work back to the switch, as long as the fuse/circuit breaker/ relay are o.k. If the blower is real bad, one of those items may cut out as soon as you replace the fuse. You can use an ammeter on the fuse block to measure the draw, but most homeowner ones only go to 10 amps,so be careful of that, unless you have an old analog one, then you can pull a probe out of the fuse block if it goes to pin the needle real quick with the fan on low. Hope this helps,Peg. Link to comment Share on other sites More sharing options...

He googled it and it seems to be a real problem with those years. The blend control door hangs (part of the heater box) and causes the motor or switch to over volt and fry. We got lucky and fixed the switch but the door is disconnected and controled by a string! Boo! Ghetto style. Would cost about $800 to fix at the dealer but can be done by any reasonably competant backyard mechanics. Link to comment Share on other sites More sharing options...

They do have blend door probs but usually you'll get no a/c or heat(one or the other-but fan will till blow. Link to comment Share on other sites More sharing options... Awards
