Question about 1994 Jeep Cherokee Country
1999 Cherokee Sport blower motor works fine on high speed setting only. The other 3 settings do not blow at all. Can anyone tell me why and what I can do to fix?
There is a reostat onthe fan housing on the passenger side under the dash ,needs to be replaced. Easy to fix!!

Look under hood back on firewall under cowl area for a resistor block, about 1-1/2" x 3" and about 3/16" thick at base,attached to firewall. It will either be attached with a screw or small bolt on each end, or it may even be a push in type. It will have an electrical connector attached to it. If no screws, try putting a screw driver in behind it, and pulling it outward. It fits into a hole in firewall, and can put up a bit of a fight, but will come. It's a resistor for the fan speeds. Just looks like someone wrapped a piece of wire around a pencil on the opposite side. Always smart to disconnect negative on battery before doing it, just in case. Mine for my van, cost me $20 here in Canada. Go to autoparts store & ask for resistor pack or block for blower motor then you have an idea what to look for & are removing the right part just in case yours is in a different area, but they are usually under cowl on passenger side on firewall.

This is a common problem with ALL cars. You likely have a failed blower resistor. The resistor controls the speed of the blower motor. There is a very slim chance it is the control head assembly, but 95% chance it is the resistor. One last thing, the most common cause for the blower resistor to fail is that the blower motor itself is pulling excessive amperage and damaging the resistor. I would check the amperage draw of the blower motor if you have the ability, if not, replace the resistor and hope for the best. If the new one fails in short order, you'll have to replace the blower motor as well. Mopars have a tendency to melt the resistor connector as well. Hope this helps!
