300D Strange Electrical Problems
I'll just kind of describe what's going on and not try to guess what it is. Hopefully those of you more experienced than I can give me a starting point to see what's going on. First, whenever I put the car into reverse with the lights on I see a slight glow in the right side blinker indicator. Second, using the right blinker it flashes normal unless I touch the brake then it starts flashing very quickly. Left does not act this way, it is normal. Third, cruise control on and pressing any climate control button will many times (not all) disengage cruise. Hitting cruise resume and all is OK, it resumes to the prior speed. Fourth and maybe not electrical, fuel guage will not go to full, goes to three quarters and as tank empties it becomes very twitchy. And finally (for this note anyway :-) where is the rear window defroster relay. I have one and want to replace it before delving much deeper in this other electrical problem.
Sort of electrical, where can one obtain the amber colored fog lamps used on the old beast, one is burnt out. Getting an honest 29 MPG with the car, very surprised as I am not light on the pedal either. 75~80 and 90 miles a day. Love this car and will be getting a second pretty soon. |

Weird electrical problems
rmmagow,
Whenever you have very weird electrical problems like yours, always check to see that your main ground connection is rust free. Remove the bolt from the body under the hood, clean up the body where the bolt attaches. If this doesn't solve your problem, check out the ground strap under the car and then work through all the other grounds. Major ones just behind the instrument cluster, too. Good luck! Get that great car running again. Ben |

I would check the bulbs on the side affected in the tailight assy. Also check the grounds for the assy. Look for a double filamented bulb, they shouldn't be there.
The only connection between those circuits is the grounding of their bulbs.

Thanks you both. As soon as the rain subsides I'll begin my good ground search. Never knew about hte double filament bulbs, I may just replace all with proper spec bulbs to be sure and clean up as many connections as I can come across. Thanks much.
