94 grand cherokee limited, the VIC has no lights, I have checked the fuse, some one told me it could be the relay but I dont have a diagram. also my temp guage isnt working, I put a new temp sensor thinking that was it but it did nothing...does anyone have an idea

 

My '93 has the same problem, I pulled it out and discovered the vacuum display is cracked. Everything in it works if I run the self-test mode on it, just needs replacing in my case. HTH

 

how would i go about doing a self test?

 

Hold the two buttons and turn the car on (don't start it) You should hear 6 beeps from your door chime thingy.
