I installed a new window motor on (2004 TL) my driver side. The window works but now my airbag light is on and the auto down and up function does not work. Any suggestions??

 

The auto-up/auto-down function can be re-set-- it's in the owner's manual, but I think it's reset by holding the switch to roll the window all the way down, then all the way up.

The airbag light can be any number of issues-- see if it continues on the next ignition cycles or is a one-time issue. Try blowing out the seatbelt buckle/latch with compressed air.
Otherwise, you'll need to get the SRS error code with a code reader to see if there is a specific problem.
