I have a 96 xj my fan doesnt have but low and the next speed up I have replaced whole climate control unit fan speed switch and blower resistor and it still the same is there something I'm missing

 

Bump

 

Have you tested the blower motor?

Since it is on the engine side of the firewall, connect two leads from the battery and see if it spins at full speed.

 

OK will try that but if I go above second notch on fan switch it goes back to low speed air just kinda trickles out

 

Do the procedure outlined in post #3. Then report back to us. Not until.

 

OK I tested motor with 12 volts it turns full speed so now we know its not the fan motor when I got the the jeep the plug to the fan speed switch was burnt I got a new plug from parts jeep and new switch now my question is on some of those terminals is there supposed to be more than one wire going in cause it looks to me some of the terminals are being used

 

I mean arnt being used

 

I don't know if these diagrams will help with your '96 blower circuit troubleshooting. They're from a '93 and '94 FSM's. I don't have '96 diagrams. In '97 there was a big change so I didn't bother posting that.

Note that switch symbol in the middle of the blower motor fuse block is a thermal fuse.
