2008 GMC Door Lock relay (r3110) location

SOURCE: Door locks don't work

Disassemble the paneling on left side ,under the steering wheel. Remove all screws and pull out the panel until you can you can reach behind it to remove the two Black Relays, on the side closest to Steering wheel. Remove the Relay covers, Clean the contacts with a 1/8 fine strip of 600 wet/dry sand paper. Only place the paper between the contacts, and pull out while holding slight pressure on the relay Armature. Turn over the sandpaper and repeat once again. Very gently press the TOP resting contact pad closer to the armature, to lessen the gap between the contact points, so the armature doesn't have to travel as far to reach the closed contact position. Repeat the above with the other2nd Relay. Replace the covers, reinstall the relays And test the Door locks prior to buttoning up the paneling. Note, a pair of long needle nosed pliers will help in removing the relays. Just Grip the relay and rock in Forward and Backward as you apply upward pressure.

it should be in the fuse box either the one under the hood or the one in the cab

SOURCE: Need location of power door lock relay on 2002

If your door locks are not working and your cigarette lighter is also not working the fuse is burned out. On my 2001 astro van it is #13 in the fuse box under the steering wheel. I have replaced mine and so far no problems. Good Luck.

SOURCE: cant locate the relay

there should be the relay under the hood,but there is a module in the dash on the passengers side that does go bad,and its under the oval part on top.i m not sure how that comes off.
