We are looking to purchase a 2007 GMC Yukon Denali and the back up camera monitor in the dash does not have a picture. When you put the vehicle in reverse the screen shows the warning like normal but the screen remains black. i have made sure that the camera is turned on and that there is nothing blocking the camera as well. What could be wrong?

Did u put in fuel shortly before the light came on? I own 2 service centers & the most common situation with "Check Engine" lights are because the fuel cap wasn't re-installed or not tightened. When you refuel make sure it "clicks" when putting back on. We don't charge for a "Code Reading" but a dealer will, don't go there. Go, like the others suggested. If it is the fuel cap & you re-install it correctly, the light will go off after a short drive. Good Luck. PS-Don't panic when the "Check Engine" light comes on unless it blinks, if that happens don't drive. PSS-RE: Murray's, Auto-Zone.......If it's a "Code" (the reader will give a #) the code book will tell you the problem. PSSS-Some1 please have Troy W's Mommy & Daddy take away his keyboard. Just because you can put together a "Lego" car doesn't make you a master mechanic. You only repeated what we said except you have a "Napoleon" complex against any1 plugging something in to a vehicle. It's the same as plugging in a light @ home. In conjunction with "kinder" nine out of ten time in my experience it usually is the oxygen sensor(s) which would be about right with the year model

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

leaking suspension air bags is the most common cause, but the system can be tested for trouble codes, I suggest u do so, only the dealer can do this, but guessing about what the problem is can get very expensive very fast.
SOURCE: lost reverse on GMC Yukon Denali vortex drives
WOW sorry to hear that.
this is a common problem with the 4l60e transmission, what has happend is the gear has sheared off the back of the sun shell, you should have lost reverse and if you will watch your tachometer the next time you drive you will notice you allso lost forth gear.
you will nedd to have the transmission removed and disassembled for the new sun shell, make sure you get the hardened sun shell, this is not a rebuild but simply a repair. you can get a stock sun shell for about $65.00 or a heavy duty one for about $100.00, make sure you find a good tranny guy to provide the labor, oh the transmission paper rubber kit "reseal kit" shouldnt be more than about $80.00
good luck
