From Edmunds - wiring problem

[edwardh1]

I have a 2004 Toyota Highlander AWD. At 44,000 miles I had some kind of electrical problem where the tire gauge light and SRL light came on, and I could not use the automatic door lock switch. I took it to the dealership and there was some kind of short in the wires. After much debate they fixed the problem. I had the extended warranty, and there was no charge. I am now at 50,000 miles and the problem is back. The service department is telling me that water is getting in at a junction box on the left panel and there is evidence of corrosion.They keep asking me if the car was in a flood or accident. I assured them it was not. They were able to connect and reconnect the wires and eliminate the problem for now. They also applied a sealer. They told me if it happens again they would replace the junction box under warranty. Does anyone else have this problem? Any comments ?

Can you see the water damage if you take the panel under the steering wheel off? Can you find where the water is entering? Did the dealer perform a leak test soaking the area with water?

If this is a chronic problem, you need to be assured that a solution has been performed, and that they haven't just supressed the symptoms. I wouldn't trust most dealers to do this. It sounds like water is leaking in through the windshield, through the firewall grommet, or through something else in that area like the sideview mirror or door.

Agreed - need to figure out where the leak is coming from...over time this will lead to other issues...
