I have a Chevrolet Impala 2011 the driver side set used to move forwad and backwards but not up and down. While cleaning my car tonight I moved the seat forward and now it wont go backwards. It was making a clicking noise. Is there anyway to manually move the seat back.

Before you do any of the expensive things disconnect and reconnect the wiring to the seat I had the same exact problem with my 2009 Chevy Impala and was ready to take it to the dealer when I disconnected the power cables to it and reconnected them I found that one of the Harnesses was loose and the problem was solved

I have a 2007 Impala. Thank you razor67 for the tap. I did not even remove the seat motor. All I used was an 18 inch rod and a hammer from the rear and hit the motor a couple of times and it's freed.

The seat has a transmission to move the seat up, down, foward , & back. Screw jacks adjust the seat up & down. Cables move the seat forward & back. The cable it seems had to break or the end of the cable has rounded out. Possibly the cable rounded out the seat it rides in the transimission housing too. You will need to remove the seat to find out

one or two things bad motor or bad switch

It isn't wired wrong. Mine does the exact same thing, but it didn't used to be backwards and the wiring has never been changed.

Inside the venting which is located behind the dash board panel underneath. Behind temp controls and radio. Inside this venting, is a couple different flaps that move to direct air to different locaitons of the car when you change the temp settings. THe flaps can get stuck or the little actuator that moves it can become faulty and will not move the air flap. You will have to manually take apart the venting system and ind the flap and actuator and see if you can manually move it. Check actuator to make sure it is not cracked or leaky or disconnected.

check for penny or dime in track

sounds like the motor is dying and needs to be replaced... that pop you heard was either the linkage coming apart on the passenger side... or the motor again.

more than like it's a bad switch assembly
