Gmc Sierra Tailgate wont shut

I would try hooking the trailer up to another vehicle and see if everything works right if everything works on the trailer I would start testing the trailer plug on your truck could be a wire has broken.

Often lights under a dash or indicators just blow out bulbs. If more than one thing isn't lighting and are centralized check fuses to see if its blown. Bulb or fuse. IMHO. MIGHT be a sensor on tranny too. Hope not.

Here's a video with detaile dinstrauctions and other people's fuse questions. New fuses?

Sounds as if you have figured it out. when you backed the bolts off put some shims behind it. problem solved. Good job

You should be able to pry it off. Be careful, if you break the latches when it pops off you will have to replace it. Look on the opposite side of the tailgate and there should be a plate screwed to the tailgate. It is almost the size of the tailgate.

Have a 2000 Gmc Serria truck and the tailgate wont open

You should be able to replace the glass, but I believe it is glued in place. You should be able to tell as you remove the old pieces. It is a special white glue.
I was able to get a great price for the whole mirror on ebay. even the ones with signals and heated.

Hope this helps

I have a 03 sierra 1/2 ton with the same problem.... I just took it to my dealership on friday and they said its the memory module... I think thats what they called it,,,, $500 plus labor for a new one.....

look under the latch and see if you see a metal rod. if you do, pull the rod and it should open.

Thats it ,oh and a hammer to knock it out of the knuckle.Some guys tighten the axle nut back up with a torque wrench.

They are not the same thing but the air temp sensor is made into the mass air sensor
