Checked the fuses for the instrument cluster, checked battery voltage and charging voltage both OK. Removed the K40 replay and gave it a bunch of stiff raps while watching the lights, no flicker and no change. Scanned the car and no codes at all, was able to read values from various modules. Any ideas appreciated.

Posted on Dec 24, 2009. SOURCE: windscreen wiper on Mercedes C200 not working. you should check the connection to the main board and the connections to the motor for the wipers. these sometimes become gunked up, so when you pull them apart to check them clean them with sand paper or something that can scrub them like a green scratch pad.
Gone: '83 500SEC,'99 500SL,'07GL450. On my 2007 GL450 the "cigar lighter" fuse is #46-15amp, which is located "in the trunk,on the right side". Just replaced blown fuse#46 in the trunk (15 amp). Appears that only the ash tray lighter outlet is on this fuse and it is only powered with the ignition.

BTW, here is the fuse location chart . . .The fuses you want to look at are 27,28 & 37 located in the cockpit fuse box. They also supply current to the roof, airscarf, seat adjustment and a few other odds & ends.I had this problem again last weekend.It has come and gone over the past 3 years.There's a detailed rectification procedure with photographs posted on this site that I photocopied some time back.Finally decided to give it a try.The relay is on a PCB located in the black box next to the battery(RHD cars).I dismantled the PCB and cleaned the contacts with a sharp knife,I believe this is betterh73Ba.
