Question about HVAC controls, please help
So my 97 TJ sport had the usual problem where the blower only worked on high, I changed the blower resistor motor today and now that works fine. The only issue is the heat will only come out of the vents facing you, defrost and feet settings etc... will not work when selected. Any suggestions on how to fix this? Thank you.

Im not sure if the 99's have the same lines as my 01, but underneath the battery there is a vacuum canister. There is a tiny line that goes down to it. It runs on the firewall across the top and then down to the canister. That plastic line connects to the canister via a 3 inch piece of rubber hose. On my 01 that rubber piece had a big split in it. I was having the same issues except mine would only come out of the defrost vents. After replacing the rubber hose everything works great. But like I said that is on my 01 and I am not 100% sure if the 99's have it. It is definetly worth a look though. Good Luck!
Yep you have a vacuum box under the battery tray. With the vehicle off if you slide your vent control you should hear a hissing sound. If you do not look in the engine bay for a problem. If you do look behind the dash for the leak.
