strange problem

[turbojitsu85]

OK here it is. My front bliker light on the passanger side of the car went out so I replaced it. It still didn't work so I walked around the car and noticeted that one of my taillights was out so I replaced that. It still doesn't blink. I turned the lights off and it blinks very dim and very fast. Also I noticed that if the car is off but the keys are in the ignition that when I turn the blinker to turn right that the door locks go to open and it sounds like the fuel pump is starting this doesn't happen when I turn the blinker to make a left turn. When I set the alarm all the lights blink as they should. The doorlocks and the alarm are not factory but ever since I had them installed 2 years ago I have never had a problem. What could possible be the problem now?

I changed all the bulbs in the passanger taillight and checked the fuses wich were fine but it is still happenning. Any suggestions would be appreciated.

I'm thinking you have a bad ground, probably to do with the aftermarket stuff, sounds like they're trying to use other circuits AS the ground, which can cause things to work when they're not supposed to, or vice versa...

The digital dash in older C4 corvettes (like my '84) are notorious for burning the ground connection on the circuit board (like mine was)--when this happens, the 4 LCD lights end up using the turn-signal and high-beam indicator lights as grounds, which lights THEM up instead...

Anyway, look for a bad ground!
