I have '99 996 C4. The cruise control doesn't work but use to. I have replaced a few tail light bulbs and am wondering if the cc issue is related. The bulbs were bought at AutoZone and are not OEM but the part catalog for the bulbs at the store told me what to get. The fuses are good. Replies are greatly appreciated.

CHeck the brake light switch as that is definitely a part of the CC circuitry. Good Luck!! Demosan :cheers:

I have the same problem with a 99 Cab. I have replaced everything. Talked to a Porsche dealer and was told it is my steering column. The other thing that happens is my horn will start honking when the car is turned off and the wheel is at a certain angle.

Don't know the cost of a new steering column -- but I don't use the cruise that often anyway. Has anyone had this problem?????

Thanks,

You do know there are car/traffic horns that the steering wheel controls and their is an alarm horn near the battery. Which is going off? If it is the alarm horn it has nothing to do with the steering wheel.

The on cruise part in the steering wheel is a multi-function switch. Usually when it fails - the green cruse control active light will not come on.
