The vent does not work, all other positions on the heater work fine.


The 4x4 light will not come on, yet I know that the vehicle is in four wheel drive and I have checked the actual bulb in the dash and it is fine.

I am afraid I am a little out of my element here, my hunch is that it has something to do with the vacuum lines, but I have nowhere to begin.

My Jeep is a 1997 Wrangler SE.

I would appreciate any help with very detailed instructions on where everything is located and any posibilities to try. I am a newbie, so if there is any other information you need please let me know. Thanks in advance. It is greatly appreciated.

The vent not working is probably the vacuum selectors. The 4wd light might be the sensor from your transfer case.

How, where do I check for either of these?
Thanks,
