Hello,

My Name is Joe. This is my first time at a Forum. Be gentle!

When I turn on my car all three lights turn 'on' at the control unit (defroster, recirc and a/c switches) at the same time and will not turn off, when I depress the individual switches. Also, it seems like the vent at eye level is not allowing air to come out. Any help would be appreciated. Thank you,Joe.

Has this problem surfaced before so someone can tell me where to look to find the answer?

I forgot to add that it's a manual climate control unit (it has the rotary dials).

Sounds like your climate control unit is going bad. Start thinking about purchasing a new one or getting the one in the car checked out

Welcome to the board! Sorry, but this is a new one on me, I don't have any specific suggestions, M5runner is probably right.

hello joe,

if you would have the automatic one i´d know the problem, but with a manual one i´mlost, too.
did you ever try your dealer. sometimes there are nice guys over there that at least know the symptoms and can give you an advice.

other than that, welocme to the board. and don´t worry. we´re almost always gentle feel free to post whatever question or concern you have.

Thank you m5runner and Kirby. I thought it would be that, but also I've seen some post's from other board's. However, they were for later model bimmer-it was a bad capacitor also in the Climate Control Unit. No such luck on my part. Oh well, I've made some calls to this place in San Antonio-they have one for about $125 used. Again thanks.

Yea I'm thinking about talking to the dealer if I can't get the other option to pan out, Thanks Wadula.

If you are going to buy a new one, please let me know. I would like to take a look at the one you took out and possibly repair. Please let me know.....I will pay shipping.

Hey bimmer luvers, I had the module checked out. It has a bad ic - octal ground contact monitoring circuit. I smelled smoke and looked inside and there it was. I'm going to see if anyone sells this p/n: L9703/x It's in the IHKR control unit behind the Tripometer and sunglass holder. Was very easy to pop out. However, I'm not sure if it burned up due to bad component or something else.

I did a quick search on suppliers I use - Digikey. Newark Electronics, Allied Electronics. None of them carry it. A general web search makes it seem like this is an uncommon IC. Good luck.....

I finally got the part IHKR for $80 used at A&J's right outside San Antonio, TX. I also had to replace the fuse and everything is back to normal. Thank you all for your input and help. On to the next thing - finding a headliner, tierods, ball joints, shocks, struts, etc. etc.
