Hi, Posting on behalf of a friend...

MY03 Saab 95 2.3 Aero Auto Saloon.

A few symptoms he experiences when it is/has been raining:

1. Satnav is going backwards, the icon goes in the opposite direction of travel

2. Reversing lights coming on whilst driving (forward lol!:p) , Rear parking sensors bleeping away

3. Reversing lights intermittent, sometimes work fine, sometimes nothing.

There is also a long standing problem with the Theft Protection. Keeps saying there is a fault (Dealer unable to resolve so far).


Any ideas?
It definitely appears to be water related as it only occurs in the rain, or after it has been raining.

Any obvious locations to look at?

VMT for any replies.

I have no idea on the Nav issue. But it sounds like some sensor is telling the Nav system you're in reverse...

For all the other stuff, check the taillight wiring harness where it runs by the trunk hinge. The wiring gets pinched there and shorts out causing all kinds of rear-end grief.
