I'm a newbie to the thread so bare with me aha. I have a 2003 trailblazer ls. everything works pretty good on it. Only issues i'm having are the RKE system and the rear wiper. I attempted to program a GM OEM key fob but when i put the car in programming mode, it cycles once (lock, unlock) and then does it again 5 seconds later. it doesn't give me a chance. the tailgate locks/unlocks with the driver/passenger buttons. and the rear wiper works but not the fluid. i have tried almost everything except take it to a dealer (my absolute last option). i've read all over the forum. most people say it may be the LGM. others say its a fuse. is there anyways to check to find out what the problem is or a solution for it? thanks in advanced.
