I just installed 2 529T's on a 2005 Avalanche. But only the two rear windows work. The two front windows are a diffrent wireing system I think. When I test the rear window module up wire, it rests at (-) and when I activate it it sends a (+) signal for the windows to go up. Now, the two front windows rest at (+) and when hit the up button they then rest at (-). How do I wire up these front switches. I called my distributor and they told me that i needed to add one relay to each door to send a (-) input to each door module. I followed their instructions and I got nowhere. Can someone please instruct me on how to wire up these two front doors?

Thank You,
Luis

as I always recommend, go directly to the motor wires.

I did run seprate wires to each door. Its just that the two front door modules have a diffrent lock system than the two rear doors. I think its a type C door lock system.

<<< I think its a type C door lock system >>>

U asked about Window Roll Up...........The Door Lock System, other than DATA LINK, has nothing to do with Window Roll UP

You need to wire your Windows as Reversal Rest at Ground.

Window Up	D\ BLUE P\ BLUE Dr Rear\BLUE Ps Rear\BLUE @ Each Switch Due to Data Link
Window Down	DF/ BROWN PF/ BROWN DR/BROWN PR/BROWN

sorry I meant to say Type C Window System. Right now I have the switch and motor wires going to each side of the cut Blue thick wire in the window switch. How exactly do I wire them as Reversal rest at ground. Do I need relays? Do you have a link to a diagram?

Are you testing the correct wires? I just did a 2005 tahoe and had no problems.
