I have a 97 xj sport. I have three ***** for AC and heater and nothing works. Only hot air blows on my right legs while I'm driving. It is really hot.
Just wondering if anybody had the same issue before and can suggest where to look for first. It's very difficult to drive in rainy days. I cannot see unless I wipe windows myself, you know.

Please help guys.
Thanks

 

Sounds like a vac leak. Check the lines under your hood that connect to the plastic ball in the passenger fender and canisters on pass side firewall. Cracked lines are common.. Also the blend door function helps control the airflows direction. I believe it's tucked under (once again) your passengers feet. It's a canister with an actuating arm and vac line attached.

 

 

There ya go!^^^^^
