Water in M25 head after car wash? - not working

**BMW-MZ3** · 07-09-2009, 04:17 PM

Hi,

I went to the car wash the other day, a touch less high pressure type (laserwash) and after the wash, when I went to turn my blinder M25's on, no beep. The led goes from red to green in a few seconds like it always did but not beep. I kept them off for a few days and tried to turn them on a few times but the same thing.

Thinking water might have got inside the unit, I removed the two rubber plugs in the front, removed the star screws to remove the black cover / lens. only to find no way to get to the PCB in the back? I popped out the rear black inserts to find out that they are only inserts to hold the side brackets on.

So, how do I take it all apart to see / dry the circuit board?

a few pics attached so you can see what I see..

They might be shorted... if they are you need to replace the heads

Hi there,

I bought them a litte over 3yr ago, so I know they are out of warranty.

Not sure (how can I tell?) If there J15 or J16 heads?

The info on the back of the heads are:
Main Box: EX-01A
Rev .5E 7.25.04H
