Fan only works on highest setting - 2000 Caravan
I boosted my 2000 Caravan a couple of years ago (3.8L) and had the fan
switch set at the 2nd highest setting during the boost. Shortly after I noticed a burning smell that would come and go, smelled like burning plastic. Then about 2 weeks later the 2nd highest setting on the fan quit working and the burning smell stopped too. I put 2 and 2 together and realized I smelled the burning smell when the fan was on the second highest setting. Now a few weeks ago all fan settings quit working except the highest. I am assuming that that is related too to my boosting of the van. Where would be a good place to start trouble shooting this problem? Help starting to tackle this problem would be greatly appreciated. Gary. |

I dont think it has anything to do with it since it has a been a few yrs
ago, more then likely the resistor block is bad, when it goes bad the fan motor defaults to the highest setting "Gary" > wrote in message news:PKmpd.333128$%k.47036@pd7tw2no... > I boosted my 2000 Caravan a couple of years ago (3.8L) and had the fan > switch set at the 2nd highest setting during the boost.

Is that something I can check out on my own?

Resistors control the speed of the AC/Heater fan. These resistors are
switched on and off in various combinations to create the different fan speeds. When the resistors burn out your fan will only work on the "HI" setting. The "HI" setting doesn't use any of the resistors and that's why it works. These resistors are near the blower and the blower is beneath the dashboard on the passenger side. Found the above, would this be a good place to start if so what do I ask for at the dealer for a replacement unit?

I did a search on resistor block and it seems to be a common problem and an
easy replacement. Thanks Maxpower! Now when I replace the resistor block, I will get my other speeds back except the second position which was my original problem. Where would I begin looking to get that 2nd position back? Would the switch itself be damaged?
