I just recently had my drivers side door module go out on me. That switch controls the power locks, windows, mirrors, heated seats etc. I changed it out and now i have a different problem. My power locks will lock and unlock from all doors except the drivers door. It will un lock if i manually put in the lock position but it wont lock.

 

I am at a loss. I went to autozone and bought a door lock actuator and replaced that and i still have the problem. I can here a whine noise coming from the actuator when i hit the lock button. Same noise from both actuators. Any help would be appreciated!

Im stumped right now. I get power to the actuator. Everything works perfectly but it wont lock. I replaced the Actuator and the DDM. I guess a bad connection? Im not sure where to go from here. Ive replaced everything in that door accept the wireing harnesses. I dont know which wire does only the lock? Help is appreciated.....

Even though everything else works? Windows, mirrors, unlock, all of it works. Just not lock.

Rob, this is what the GM SI program I have shows....mind posting up what you have?

If equipped with camper mirrors program the door module. Refer to Service Programming System (SPS) in Programming.

 

BTW, I know this one isn't the most up to date for sure.

 

I do have the extended towing mirrors on this truck.

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉
