Burning Smell From Rear End Area After Cold Weather Driving

[Baylee Brown]

The only time I’ve had this happen to me is when I let someone drive my 99 z71 Tahoe and they left the parking brake on for about 2 miles. Smell went away within a day.

Got a strange burning smell that emanates form the rear of the the Yukon after the truck is warmed up and driven in the cold. Smells like rubber/plastic. Checked underneath and nothing is stuck or obvious. My old Tahoe did this to. Anybody else have a similar experience?

light sockets

they tend to burn with the incandescent bulbs because they are over driven (i.e slightly higher volts)
12.8v bulb running at 14.5volts (or in my case 15 volts according to the DIC)

That’s really good info however I’ve got G5 LED tails. Appreciate the insight.
