whats it do. if it blows out cold on the passenger side and HEAT not just warm but f*cking hot its probly the vent door arm has fallen off or the motor is not moving. pull the lover black cover off on the passanger side. a about 3 or4 feet long and quit a few screws but easy to do. look on the right side of the vent ducts you will see an arm and rod. see if its still hooked on and it moves when you change the temp from 60 to 90. sometimes it take 30 sec or so befor it starts moving. if it wont move then its not good. a new climate control programer. aka big computer box under the dash that contols the entier thing with driver comands from the dash display . is not cheap just take the rod from the vent and put it where you need it. in sumer time push it all the way in. in winter though your gona need heat on your side to so you will have to pull it back out.
It probably is wiring or relay.
it was my own question but here it go's in my case it was just the bracket on the trans. tightened the two bolts and now it works fine.
There is a conduit with a fastener at the end. When I obtained my 2005 Buick LeSabre my rear air vents seemed to blow less than I had expected. After further inspection, I discovered that the conduit was not attached to the vent stack. So I played with it until I got it to slide into the vent stack and it seems to work as I would have expected at present.
ensure all bulbs on bumpers are good
put pressure on the piston(c-clamp works good). If it doesn't push in petty easy, then open bleeder. if that doesn't work, replace calliper. if that did work, replace brake hose.
The flasher justs unplugs from a connector. Most flashers are located under the dash near the steering column. If one side of the flasher still works, turn it on and follow the clicking noise. I hope this helps you. Mark

if it is a factory alarm, you have to unlock the door with a key from the outside. most likely the switch is busted on the drivers side so try the passengers side. if it works, go buy a switch for the drivers side. the switch is on the end of door lock cylinder.
Check your battery cables. Some computerized vehicles have to be reset. Disconnect the battery for about 5 minutes and then reconnect.
Check the connection at the battery terminals. If either one works slightly loose you will think your car is ready for the scrapyard. Sometimes all the dash warning lights will flash on and off and your car will stall if a connection is loose.
