MODULE

2002 GMC Envoy

Computer problem
2002 GMC Envoy 6 cyl Four Wheel Drive Automatic 35000 miles

HAD MY LIFTGATE MODULE ON 2002 ENVOY REPLACED BECAUSE THE AUTOMATIC DOOR LOCK WOULD NOT WORK BUT THE LOCKS UNLOCKED WITH KEY AT DRIVER DOOR AND THE SWITCH FROM THE DRIVER DOOR AND WAS USED UNLOCK THE OTHER DOOR SWITCHS EXCEPT FOR THE LIFT GATE WHICH WOULD NOT WORK, ALL WINDOWS AND HEATED SEATS WORK AT THE OTHER DOORS FRONT AND REAR. WHEN SHOP WENT TO PROGRAM IT THERE COMPUTER SYSTEM TO FACTORY WAS WAS DOWN OR THAT THE SYSTEM AT THE DEALER WERE BEING REPROGRAM WHAT EVER THEY WERE UNABLE TO FINISH THE JOB. SO THEY GAVE ME MY CAR TO TAKE HOME AND WENT TO START THE CAR THE NEXT MORNING THE BATTERY WAS DEAD. I GOT A JUMP AT TOOK IT BACK TO SHOP AND THEY HELD IT ALL DAY TRING TO PROGRAM IT BUT SYSTEM NEVER CAME ON LINE. THEY WERE UNABLE TO GET COMPUTER UP TO PROGRAM IT SO THEY SHOP DISCONNECTED THE MODULE. CAME BACK WEEK LATE WHEM SYSTEM WAS FIXED AND THE MECHANIC THAT HAD WORKED ON IT THE FRIST TWO DAYS WAS OFF SO AND ANOTHER MECHANIC WORKED ON IT ALL DAY TRING TO PROGRAM AND TROUBLE SHOT IT ALL DAY BUT WAS UNABLE TO GET IT PROGRAM THEN WHEN I WAS GIVEN A RENTAL CAR THE MECHANIC AND I TALKED WHEN I WENT TO GET SOME THINGS OUT OF THE CAR AND I TOLD HIM ABOUT THE MECHANIC DISCONNECTING THE MODULE AND HE SAID THAT WOULD HAVE BEEN NICE TO KNOW. SO I STAYED ANOTHER HOUR HE HOOKED IT UP AND PROGRAMED THE MODULE AND I WENT HOME HAPPY. THE AUTOMATIC DOORS WORK AND LIFT GATE LOCKED. THE NEXT DAY I WENT TO ROLL DOWN THE WINDOW ON THE PASSENGER AND THERE WAS NO POWER TO THE TO HE WINDOW LOCK OR HEATED SEAT SWITCH. FOR SIX MONTH I HAD USED THE DRIVER DOOR KEY TO GET IN AND THE SWITCH ON DRIVER DOOR TO OPEN THE OTHER DOOR ONLY THING THAT DIDNT WORK WAS LIFT GATE LOCK. THEN WHEN I WENT TO ROLL PASSENGER WINDOW DOWN NO POWER TO PASSENGER DOOR AT ALL. COULD OF THE TROUBLE SHOOTING OF THE DISCONNECTED SWITCH AND FUSE CHECKING OR THE MANY TIMES TRING TO PROGRAM THE MODULE CAUSED THE MODULE FOR THE PASSENGER TO BREAK. MECHANIC TRIED COMPUTER STATION IN THE SHOP PLUS WENT TO ANOTHER DEALERS SHOP TRING TO PROGRAM IT BEFORE HE LEARNED IT HAD BEEN DISCONNECT BY THE OTHER MECHANIC. ALL THE OTHER DOOR WORK FINE WITH AUTOMATIC LOCK WINDOWS AND SEAT. NOW I HAVE TO REPLACE THE MODULE FOR THE PASSENGER DOOR. ALL DOOR SWITCHS WORKED FINE UNTIL THE LIFT GATE MODULE WAS HOOKED UP. WHAT COULD MADE THE MODULE IN PASSENGER BREAK. OR WAS IT JUST ONE THOSE THINGS ONE BREAKS FIXTHE MODULE AND THE NEXT IN LNE FOR DOOR LOCKS BREAKS?

Go back to the dealer and explain what happened, it may just need reprogramming again for the passenger door.

WENT BACK THEY CHECKED OUT PASSENGER DOOOR FRIST SAID NO POWER TO DOOR AND THAT THEY WOLUD HAVE TO TRACE THE WIRES THEN SAID POWER TO DOOR MODULE BAD. BUT EVER WHERE I HAVE FOUND THAT THERE IS NO WAY TO TEST MODULE. AND YOU HAVE TO REPROGRAM ALL OF MODULE NOT JUST ONE BECAUSE WHEN YOU PUT IT IN THE PROGRAM MODE IT ERASES ALL THE PROGRAMS AM I RIGHT THERE. SO IT COST ME ANOTHER $380 WHEN EVER THEY CAN GET TO IT THEY HAD TO ORDER THE MODULE. IS IT NORNAL FOR ONE MODULE NOT TO PROGRAM DURING THE PROCESS OF PROGRAMMING. UNTIL THEY DID PROGRAM EVERY THING WORKED FINE ON THE PASSENGER DOOR WHEN USING THE BUTTON

If the module isn't there or disconnected it will read as being bad and not program. So the module must be connected to program. If the module is bad it won't reprogram either. If you can find someone with a tech 2 or laptop that has the programs then it can be reprogrammed without going to the dealer. But good luck there.
