Strange lighting problem.

My '88 240 wagon is having a weird problem with the dash lights, the blinker arrows stay iluminated as does the high beam signal (not on) and the rest is completley dark, my turn signals and high beams seem to work fine but I can't see how fast I'm going and its kind of erie having only darkness in front of me while I'm driving. I'm thinking it might be the rheostat. Also the headlights tend to flicker a lot while I'm driving at night.Just wondering if anyone else has had a similar problem or has any advice. Oh,, My third (high) brake light only functions intermittently,worried this is going to confuse someone that sees it go off while I'm still braking, does anyone know about this problem? thought I'd go ahead and throw that in there while I'm on the topic. Any help would be greatly appreciated!

2 Things check the grounds in the engine compartment for the headlight problem sounds like a bad ground for the 3rd brake light check the tailgate harnesses where they go through the tailgate for breakage

I had a similar problem on my girlfriend's '85 244. Very strange behavior of the dash lights (can't recall the exact symptoms). The culprit turned out to be a cold solder joint on the dash cluster PC board. There was a jumper wire that connected the ground planes on two separate areas of the board, and one of the ends of the wire was making an intermittent connection.

You'll need to pull the dash out of the car and remove the PC board from the back of the dash cluster to find and fix this, if it turns out to be your problem. On the '85, the jumper was to the lower left of the speedometer (looking from the front). Suggest you exhaust other avenues of investigation first.

re third brake light - i had same problem and thought it was a bad bulb. But new bulb did the same thing. What I did was use a sanding sponge [very fine grit] to massage the terminals connecting the light socket to the base of the rear deck - result, no more trouble. The contacts had oxidized over time. Works fine now!

cheers! steve
