Hi everybody,</P>


I bought a beautiful Black 190E '91, runs great butI need to fix some problems:</P>


Wiper is too slow and the 3erd speed (quickest) do not function at all.</P>


The motor temperature sensor was broken and I replaced it, but the temperature gauge still not work.</P>


The seat's head rest don't work, all other movements are ok.</P>


Aparently all instrument and warning lamps are OK, but I would check if the sensor work really, for example low fuel warning, radiator coolant warning ,brake fluid warning, etc.</P>


I will apreciate any sugestion or info.</P>


Thanks in advance</P>

I had the same problem with the headrests and fixed them. Just click the post about headrests, or https://mercedesforum.com/forum_post...D=773&amp;PN=1</P>


As for the windshield wiper, I'm no expert but you might need to replace the control arm that comes out of the steering column. I had a problem with mine shorting out during the rain, and I had to replace the entire motor. Maybe someone else might know something more about it.</P>

<FONT size=2>Concerning your wiper, the problemmight be that you need to let the piston (wiperarm) that moves in and out,get a little oil.</FONT></P>


<FONT size=2>I do it like this: put the wiper on, turn off the ignition switch when the wiperarm reach one of the upper corners of the windshield. The piston is now as far out as i goes. Lift the plastic cover on the lower end of the arm. Now you can se the pistoarm and easy give i little fine oil.</FONT></P>


<FONT size=2>This may not solve your problem, but my expierience with these singlearmwipers is that you need to do this once in a wile anyway.</FONT></P>


<FONT size=2>Good Luck!</FONT></P></TD></TR>

[8D]Also have a 190E, 1991 2.3 AUTOMATIC.

Does anyone know how to replace the automatic gear selector light bulb?

Also, my fan switch for the a/c heater stays on high, no matter where you set it. Any ideas?

Thank you very much for your help.
