My backup lights on my 2000 sierra 4.8, are not working, so i put in new bulbs, still nothing. Checked to make sure the box/module mounted to the 4l60E was correct by shifting through all gears (checking for backups) and still nothing. Checked continuity in my wiring, all good, checked fuses, all good. So, I get under the truck to check the pinout at the box/module to ensure that I have a proper switched signal for the reverse lights. The plug will not come out of the module, I have the clip pulled back and using small screw drivers to pry in-between the plug and receptacle and i cannot get it to budge. I called my buddy at the GM dealer and he says that GM glues the plug in.. Now, this sounds bogus to me but so I figured i would get a confirmation here if it is true or not?

Yes, a lot of them have been glued into place to keep dirt and moisture out. Get a heat gun and warm it up a bit, should come right off.

Mine were glued in also. I was able to pull out the smaller connector, but ended up cutting the wires on the bigger one. Didn't think about heating them up!

If it is as simple as heating the connector with a heat gun then that will be easy, my main concern was using a chemical solvent to break down the adhesive, in turn that would concern me about corrosion and damaging he contacts/conductors. I understand the reasoning to use glue to seal the contacts from the elements, but there is easier methods to insulate as opposed to using a glue.

Don't use chemicals. You'll dissolve more than just the glue inside the connector.

It's actually not a bad idea to glue those connectors with hot glue. You'd be amazed what sort of nasty stuff they're exposed to, from being submerged in water to road salt.
