on my cherokee the temperature thinger on the overhead console thats to the right of the compass is farked up it usually reads -0 F but every once in a while it will work and say how cold it is, is there some sort of sensor somewhere thats bad or something? also i noticed that little black bubble on the overhead console and im guessing im suppose to have a remote for the door locks and stuff but i dont have one, is getting a new key remote a pain in the *** or expensive? thanks for any info.

 

The little black bubble is part of the security system. If you watch it in complete darkness, You see it blinking when locked. Don't really need a remote, There nice to have. But usually about $100, or better. If you ever kill the battery. And jump it, Or use a charger. the first thing to activate is the security system. You need to turn the key in the door, Lock, Unlock. To de-activate it. (Found out the hard way, Had to quickly look it up in the owners manual. With it honking in the drive way for me) As for the temp/ comp module, on it's way of burning out. They have replacement ones at Mopar parts stores, But for mine 1991 it's a $695. I just about s**t. It took me over a yr. to find one on E-Bay. Especially under $100. In 1993 they changed to the model you have. (93-96') I believe. Your's is more common, and a little cheaper. So check with local Junkyards, or E-Bay. Was also used in other Mopar cars of that year, Like Town & Country vans, Dynasty, ETC. Good luck to you. People know what these overhead consoles are worth, as you will see. ( even if you only need the module out it.)

 

As far as the temp sensor goes.... I would see if the problem is just the sensor itself. It is located behind your front bumper. It sounds to me like either the sensor is bad, or you wires for the sensor are shorting/grounding out to give you a 0 reading. The sensor itself is not too expensive.

 

sorry to bring this back from the dead but this is the only thread I can seem to find on this. my overhead temp is way off it says it is like 10 out side when my phone says it is 40ish. does anyone know the name of this sensor and what it looks like?
Thanks.

 

Its called an "Ambient Temperature Sensor". Throw that in Google images (along with "Cherokee") and you can see what it looks like and where it is located (behind the front bumper).

 

^^^^ thanks that is what i thought it was called. I don't have a stock bumper so no I need to do some looking for it.

 

I have a weird problem but not sure how to approach a fix. The center console in my 93 GC shows 9.3 mpg average all the time...the other indicators all seem to work correctly. Is this an indicator that the whole device needs replacing or is there some sort of sensor that might be out? The mpg real time indicator seems to be working so I am thinking the calculator in the device is hosed...any ideas? Also the cruise control does not work....it used to but it acts as if dead. Anyone know where the relay for that is located? I used to hear it click when the cruise control was turned on but now nothing and I do not find any fuse for this as well.
