I've bad the.same problem with my S250 for a few years now. I believe it's a moisture issue in the panel. I turn the headlights on when it starts and the heat warms up the panel and it goes away. There is a 2 wire plug into the panel behind the headlight I can remove and the warning is disabled...
I did check the overhead wiring harness and found nothing. A wire rubbing was what my dealer thought also so that's where I went first. Then I unplugged the 2 wire connecter on the display and the alarm stopped, so I zeroed in on that. I also wanted to check ground connections, but didn't know...
That is correct. I just finished using it and for whatever reason turning the front lights on stop it from happening. I will check out the controller you are talking about. Thanks for your time.
I too believe it is the left side controller. I think moisture got in it, either from the headlight opening or maybe just condensation. I took it out and tried drying it in a bag of rice and a little heat and it helped for a while. If I turn the lights on it clears up after a bit, i assume from...
The door alarm goes off even when the door is not on. I thought it was moisture getting into the wiring harness but have checked it above the door and cannot find a problem. Maybe a wire rubbing somewhere but I can't find anything. Any suggestions? Thanks.
Could be right. I put a couple of screws in it and it stopped it for now. I don't see any wobble or play on the fan. I wish it was easier to get at. There are 2 screws in the grill on each side that were put in before the assembly. I might try to invent something.
Upon further review, I believe the engine heat is causing the plastic shroud to bow up enough to rub on the fan. I can hear the fan kick on and off during normal operation, it's when operating at over 2000 rpm when the rubbing starts. I think I need to draw the shroud down with screw or bolt.
