2002 trailblazer, alarm/remote start

sweeeeet it works!!! everyhting works perfect. the olny function i cant get to work is the window roll up feature. i got it to flash 5 times and locked it. and saved it. and it didnt work. i tried to program it again, and it still wont work. maybe it just doesnt work on this vehicle. either way, the wife is happy. she got a viper alarm/remote start for her birthday and it only cost me about 200 bucks (including the wasted money on the idatalink). thanks to everyone that helped me and i will come back here often.
