Speaker stopped working after Ford replaced the window regulator.

Some say yes, some say no, most say it has a GEM, not a BCM.

A used seat.

The clicking noise sounds like your blend door actuator. Try turning your AC/Heat OFF and see if it stops (give it a minute to travel in position). The actuator is a common failure in the Expys, costs about $50 to replace. You will have to remove the right rear panel to replace it - a few screws and a couple of bolts (where the seat belt attaches).
As for the seat not working, not sure about this. I would make sure the wiring harness is hooked up and the fuse is not blown. See your owners manual for fuse location.

simple design but it works

i have 2000 ford expedition that dealer just replaced trailing arms now rear air suspension wont work now what or is there somethig to check first

it seems like your heater core is leaking check your hoses that go into the firewall for leaks if they arnt leaking then your heater core is leaking and needs to be replaced

The entire assy. This uses a cable system and what you are hearing is the cable twisting and getting ready to snap. New units are available at Advance Auto parts
