Remember I got snowed on a few weeks ago in Death Valley? Nah, it's not cold enough for a heater. Finger

So was the final problem a Vac line? since I got my 97 used in 2003, it has had a hard time selecting from Dash to Defrost to Heat ect. Sometimes it will go there pretty good & others...actually most of the time it just blows out everywhere a little bit. I 100% don't want to take it to Jeep to fix. I want to do it myself so I know what the problem is & can correct things as they happen. I do have the shop manual, but have not checked it for this problem. Some of the stuff in there I find confusing sometimes or just plain hard to find. Not sure if it is from to much or to little info.

Anyway, did you solve the problem? It is starting to get chilly in Norther IL & I'd like to figure this out before it gets cold Smile

Thanks,
Tim

Yep, definitely check the vacuum line on the driver's side of the intake. I had the same problem, somehow it just popped off.

Put it back on, works like a champ.

Since I have not really looked to what is under the dash. Where exactly is the vac line on the drivers side? Bottom, top, close to the firewall, close to the foot pedals, etc. Any help will be a big help while crawling under the dash. Also, I guess I am assuming that it is under the dash, not under the hood.

Thanks,
Tim

completely forgot to post back here...sorry Razz

Yes, it was the vac line, passenger side, under the battery shelf. It was cracked where it pushes on, so I trimmed it off and pushed it back on. It came off again while wheeling hard, this time, I wound some electrical tape tightly around the end before pushing it back on.

And yes, it gets cold enough here to use it. But usually only up in the mountains Smile

If the line is coming off after trimming it back it is probably getting too old to be reliable. Elect. tape will hold for awhile but the line will continue to be a bother.

Hose is cheap, buy more and replace the whole line. BTW, might be time to replace ALL the lines now too before they began to cause engine problems. This is a small price to pay for the fun you'll get out of your Jeep.

Before you go yanking the dash off, be careful with the airbags. I don't want to read about you having a screwdriver embedded in your sinus. Do you have the FSM? If you go to the HVAC removal/installation section, it shows you how to pull the temp control panel from beneath the radio. I'd look at those connections to make sure everything is still hooked up and also check to be sure there's enough vacuum to operate the blend door (not the right name, but I can't think of it right now.)


The dash is really easy to remove and as far as the airbags go just dis connect the battery and un plug the bags. Make sure you plug in the bags before you connect the battery again. I did not have to remove the steering wheel at all to do it so just the dash airbag needs to be disconnected. Actually the frame can stay, just the plastic cover needs to come off to get to the HVAC unit. There is a valve that has an arm on it which moves the door. This arm breaks just inside the housing so you have to replace the whole housing with the door and valve.

Ouch, the whole housing. Do you know how much that cost? I think that is probably what is wrong with mine as it semi works intermittently. This week, it would not work at all. Then all of a sudden it worked again. So I'm guessing sometimes it makes contact & sometimes not.

I had this problem with my 2001 Wrangler and it was a simple vacuum hose near the fire wall that had come off. For anyone with this same problem, check that before you go and spend money having someone else do it. It's a skinny little hose that almost looks like it has a nipple on the end of it. crazy jeep
