Just wondering ive changes the blower motor the resistor and blowoer motor speed control switch and the fuse is good. Where is the location of the relay i have a 94 4.0 sport. The ac relay under the hood does nothing when changed.

 

I'm curious to know as well? My ac only works on high and the blower motor resistor is good. I've tried cleaning and resetting the fan speed switch. And not really sure where the relay(s) are. I replaced the heater core the other day. The manual called for removing the relay which was supposedly located at the front of the blower/evap housing. But, there was no relay there.

 

I'm not much help except I'm about positive my 90 has no relay for the blower. It's a high amp deal....and if a wire or connection or switch is going to fail, high amps will help there...A bad connection that IS trying will get hot.

I might start by juicing the blower motor it's self, then working back. All I've got.

 

Your '94 is probably different than my '00, but on mine that relay is behind the glove box. I had to remove the stop which allowed the box to drop all the way down and expose it...or something like that. It's been a few years since I changed it.

 

Nevermind

 

Wrong!
That is the Heater control resister. Not the relay.

 

My blower is not kicking on at all. Its a new blower and new blower speed control switch. I heard the resistor wen crappin out will only go on high. And same with the relay i heard that it will go bad but still blow full or no speed. Mine does not kick on whatsoever. I cant find the relay thats my last thought of what it may be. Fuse was blown but i have a new one in now. And i can hardwire the fan straight on and get kickin heat. Just wondering why the dial isnt working. Yes i changed the blower speed switch/ speed dial. And nothing.

 

Definitely wasn't the resistor.

 

I'm having a similar issue with my 97 Larado. I'm having a volt drop or current draw issue. its got to do with the splices have double sided sticky tape melting in between stands. I did a paracitic draw test and pulled fuses on till test light went out to find the problem circuit. Its the blower motor circuit. I can't find the relay ether. it's not behind glove box. Only wires to blower, resistor and connectors. I even got diagrams. None show were it is.
Can some one access some other diagram or pic that is not behind the glove box. MY Larado has a junction box under the glove box. perhaps it is in there. How to find a relay when the wires from the fuse do not show continuity to the other side if firewall to any component?

 

No, he's Correct!

Here's a diagram that shows the location of the blower relay on the '97-'01 XJ. Roll down the glove box and there she is.

 

Here's a diagram of the4 '94 blower circuit. I don't see a relay, do you?

 

yah yah, i know old thread.. but I have the same question..

does a 95 xj have a blower relay? and if it DOES have one, where is it?

the parts list in the autozone parts store have a replacement relay for the 95 xj.. I've got it in my hands. But.. I havent found it on the jeep yet.

 

Take a look at the diagram in post #11. I can't find Waldo...

 

Agreed CCKen. I cant find it either.. I dont know what this little guy I'm holding in my hand is for, but I'm taking it back to the parts shop. My blower seems to be working just fine now.

 

Maybe watch out for less than good contacts in the switch getting hot and melting the connector. Idk......
