Hi,

Replaced the blower motor and the resistor on my 91 xj and it still only works on high. Any suggestions? Fuses all seem to be good.

Thanks

 

That's odd! Normally when it only works on high it is the resistor. I would start with making sure that the resistor is good and making good contact. If good start checking the switch on the dash and any related wires and relays.
Good luck and keep us posted.
Welcome to the forum.

 

I am pretty sure the resistor is good, the old one looked good, no broken coils. The plug is clean, wouldnt see why there would be bad contact. I am thinking the control on the dash may be bad, it did work fine then just stopped one day.


**edit**

is there any way to test the resistor?

 

try a new resistor

 

I'd start testing with a multi-meter. Check for continuity thru the resistor...

 

I will check the resistor first, let you know how i make out.

 

Just take the resistor back to where you bought it and tell them it's bad and they should give you a new one.

 

I will give it a quick test and see since they are closed already.

 

Closed? Are you in China?

 

The auto parts store i bought it from closes at 2pm on saturday. I dont like to give to large stores like auto zone if i can help it, they didnt have the motor or resistor anyways, they wanted me to wait 2 days, i had it in 30 minutes.
