Hi, new to the forum I think and first post here.
The horn was continuously on when my wife pulled into the driveway but before I could get the battery cable off the fuse failed. I found water on the fuse panel and floor, the windshield having been replaced a week earlier. I haven't replaced the fuse yet but got an anti-skid needs service light the next time out. I am suspecting a defective clock spring but would like some confirmation or other possible causes and ideas on how to fix it before pulling it all apart. Also, could more harm be done by driving it for a while waiting for parts?
Thanks

 

there are lots of threads about the sunroof drains getting clogged and how to clean them (remove a pillar trim to access the elbow where debris can block drain).

the anti skid message could be unrelated and has several possible causes. if it is the clockspring, you may see the anti skid message when you park with the wheels turned to one side, but not if you park with wheels pointed straight. that is what it turned out to be in my case (replaced under extended warranty).

 

Just a bit of an update to this, I took it back to the glass place and they filled a hole that was found by blowing air from the inside. I think it was just coincidence that the horn went on coming out of the car wash. My wife has since told me she heard a grating noise so probably the clock spring. I will take it in for diagnosis soon and let the forum people know what it took to fix it.

 

Went on holidays, tried fuse on Jan 2 and horn still on. Took it to dealer and they put fuse in and could not fault. I guess it was the water contamination and I got lucky that it fixed itself.
