97 grand Cherokee limited.. I have no lights on my HVAC controls I have a picture of the back if I am missing a wire I can't find it??? Also I did have air and heat coming out of my feet vents and defroster. Now it only comes out the defroster I checked under the battery, replaced some
Vacuum lines? I can't figure this out, also when I turn the selector **** it's either on or off? Nothing between? Just feels loose? Thanks for the help again

 

Give those little gray nubs a twist and replace the bulbs that are in them, you should have light after that.

 

In the second pic I have there are 4 little metal taps they look like a plug
Goes into them is there something I am missing?

 

Anybody??

 

I can't tell by the pic on this lap top, but something should connect to or plug into that.

 

Dig around in there for the wire that goes to those terminals.. did your lights ever work?

 

Yes lights did work before I pulled the dash apart I'll probably search around in there tomorrow some more, I have looked before but maybe something just feel Down there has to be wires that go there bc I accidentally touched a screwdriver to it and it sparked..

 

Working on electricals with the battery connected?

 

A shock is good once in a while any insight to these terminals

 

Ok so I dug around behind the dash and I got nothing? Just seems odd that those terminals are there and there is nothing that connects to them? Can anyone take a look and see? This is really bothering me.. Any help please

 

Does it have the Automatic Temperature Control system? If so, I looked at the FSM, and the only thing I could see was that maybe that's where the outside solar sensor and inside temperature sensor wires connect to the control panel. On the Manual ac/heater control panel, it wouldn't have those.
The Automatic system has 2 large and 1 small dial, and a temp. display screen. The manual system has 3 large dials.

 

It's manual with the 3 large dials. It just doesn't make sense that the lights stopped working on it and the middle switch just doesn't feel like it has any pressure when turning it any way to test vacuum? I checked all the lines and replaced some and still nothing?

 

Anyone?

 

I believe when you pulled the control panel from the dash the part that connects to those tabs in question somehow got snagged and was left in the dash. The picture/diagram in the FSM showing the rear of it looks different than yours. My printer/scanner is inop at the moment so I can't show you what I'm talking about. I think if you feel around in there (with the key off) you might find the other part.

 

Unless someone else took it apart before there is nothing in the dash I have it completely open and can't find anything? What does this "piece" look like? I have been in the dash multiple times and once for 45 minutes digging around and I got nothing?
