Windows don't work from any doors. Ocasionally they work but don't dare using them fearing they will oot go back up. Replaes main switch drivers door didnt resolve problem. When I press drivers window control, switch makes a loud clicking noise. Checked for power to switch and I show voltage at switch. No doors work from there own switchs either.
ALL the windows share a common ground, this could be your problem. The ground wire originates at the driver's switch and goes back through the harness to the door, and into the cabin where I think the black ground wire may ground on a frame or bracket in the left kick panel. Just after it comes in from the door. You'd have to look behind the kick panel (foot well) covering to look for the ground screw. There could be a couple other ground wires there too. Or take your meter and check the integrity of the ground wire at the switch. Either use the ohm function or do a voltage drop test to check the ground.

Replace the Driver side window switch. These have a corrosion issue.

Not likely getting a bad TPS.Your TPS runs off a 5volt reference wire.Using multimeter with key on engine off Check to make sure you have your 5volt reference check for any deformed terminals or broken wires inside insulation.

U need to clear the AC condensation drain, crawl under the car on the passenger side and near the base of the engine firewall u will find a drain pipe, (about 3/4") clear t and the water will stop going on the passenger floor.
