Driver's Front seat help?

[SFBerto415]

I own a 2004 SLT Yukon. It has the power seats installed. My wife occassionally drives my Yukon and she mentioned to me that the driver seat no-longer goes all the way forward anymore. I checked it out and I couldn't see anything lodged in the tracks of the seat that will cause it to stop half way.
Do any of you guys/gals know how I can troubleshoot this? I'd hate to take it to the dealer and dish out a lot of mula (I don't have) for something that I can do myself.
Please help me out, thanks folks.

i know nothing about these specificly... however i had a 95 STS with power seats and te passenger seat stopped working... never fixed it as I was told I needed a new motor which was many hundreds of dollars

my seat has that trouble plus tons more! I believe it needs a new stepper motor because when they start going bad they function partially and on and off. I havent gotten around to fixing mine but some research I have done has led me to that conclusion. Let me know if and how you fix it

I had the same issue on my 2003 Tahoe. My driver seat module needed to be reprogrammed. Here is the detail I found on it.

At first I didn't notice the opposite direction problem. Just the limited range of movement.

Good Luck!

I just had this done at the dealer on my 2005 Tahoe. One hour of labor ~$115. Reprogramming the seat module fixed the problem.

My problem was: a combined issue of intermittently not moving all the way forward, and operating in reverse of the switch for the times when it would move forward past a certain point. The switch operated normally in the rear half of the range of movement and in reverse for the front half (when it worked at all). This lead me to think that the switches and motors were operational, and it must be a software error.

switch has power to but motor does not.

My 2003 Tahoe has power everywhere but to the motor itself. its making me think that the switch is bad. a few months ago it quit working all together and it had a loose wire. i fixed that issue and then it was fine. the past few weeks it would not work properly. the memory would push the seat in instead of out etc. Now nothing at all any ideas? Please help!

01 Tahoe....Driver power seat will not work. Passenger seat works fine, heat is good to both seats. Lumbar on driver seat works. I was told by dealership the switch is good but it is the seat module that needs replaced. Module is discontinued through GM and they will not install an aftermarket. Help?!
