Rear view mirror compass & temprature works only part of the time

under the hood in front or the rad

Does the compass work when the temperature goes out? If the compass still works then chances are that the ambient temp sensor is defective. Also, could be wiring to the sensor. If the compass goes out with the temperature then chances are the mirror itself is defective. Cheapest most common problem is the ambient temp sensor. It's behind the grill by the condenser at the front of the vehicle.

u might have to do that with the mirror but the air bag thing i would have a mechanic take a look at it but i think the air bag computer system is failing

It can be faulty fuse or loose connection.Because on most of such cases its that.

But still for step by step troubleshooting.Click the link below and follow the details:----

This will help.

Thanks.

sounds like a fuse blew if both went out check fuses first

first always check your fuses then if you have a autozone take it there and they can tell you what the code is and if you want to try it yourself they will give you instructions and print outs of where and how to do your job

what could be the problem,its was working just fine.

My airbag light will not cut off and my temp and compass on my rearview mirror cut off the same time it went out too... I changed the fuse because it was blown... it works for a couple of days and then cuts back off... I took it to the dealership and they did a dianogstic check and can't find the problem

Yes. Look in the Fuse Panel inside the Truck. Use a Good Maglight or LED Flashlight and Hold it Behind the Fuses to see the Blown Ones. It is usually in an AUX Outlet. Also check thr Fuse Relay Box under the Hood for a Blown Fuse using the Same Method. See if there is a Relay for this also. If so, Replace it. Let me know if you need any more Help!
