Not a Chevrolet, but still GM. This is a problem I have with my '93 Cadillac DeVille:

Today I noticed that the Directional Lights were not working properly. Soon after, I shut the car off and when I started it again about 5 minutes later, it was slow cranking and just about started. I knew then I had some kind of problem. Went to my friend's garage and had the Charging System checked. Everything checked out fine, good amps, good voltage. I mentioned Battery although it is only 3 years old and he stated that it could be the Starter, which I agreed with, but I reminded him about the Directional Lights. We then both agreed, most likely Battery.

Went to the parts store and I installed a new Battery, thinking now that the problem is solved. Went down the road and noticed that the Directional Lights are still acting goofy and also the MPG Fuel Gauge is acting crazy, fluctuating the numbers all over the place. I then went back to the parts store and picked up a new Flasher, which I will be installing next.

My question is, has anyone out there ever experienced or heard of such a strange problem like this and do you think a defective Flasher could possibly cause it?

BTW, the 4-Way Flashers work fine, just the Directional Lights are goofy. They will blink normal for the first couple, then hesitate, then blink quick, then hesitate, then blink normal once, then hesitate, etc, etc.

Any help would be appreciated.

You may have a bad connection at the ignition switch. The things acting goofy are switched power. The 4 way flasher is constant power.
Look for a wire with melted insulation on the switch or the switch connector.

Well, to my surprise, it was just the Flasher.

I had no idea that a Flasher could react like that and cause that much trouble.

Thanks for the help anyway.
