| Turn Signal problems |
I recently purchased a GMC Sierra crew cab pickup . When it rains, the right front headlight fogs up creating a hazard as on coming traffic cannot see my turn signal. The left light does not fog up. Now, the law of physics tells me there is a leak in the headlight and naturally the moisture will condense on the coolest part of the light which is the glass . I have written GMC with the complaint and they will not answer my complaint. This is a safety hazard. My name is gaines smith. Truck was purchased at hafner motors, batesville miss.
