Problems with Lights on a 6.5L Diesel GMC

Volume 1 Issue 4 - 6.2/6.5 Issues and Answers

I have a question not related to my engine, but hope you can help. Our ’95 GMC has developed a variety of problems with its lights, while we were on a trip. The turn signals were sometimes dim and or they flashed rapidly. The brake lights often do not work at all and the tail lights are dim. All the lights are behaving oddly. A dealer checked it out for us and replaced many bulbs, but things are still goofy. He now says it needs a new turn signal switch at a cost of $620, but he will not guarantee this to be the fix. Do you have any suggestions?

This might work
I way to fix this is to replaced the light bulb sockets.I had the same problem.You see the contacts from the sockets sink in from aging and from the heat they naturaly generated.These problems do not occur with LED light bulbs due to the fact that they do not radiate as much heat as the older style bulbs.
