Driver window switch 99 cadillac eldorado stopped working ,how do I remove it to check?

when you lean it forward to lift it up bring it up as high as it will go then give it a hard forcefull hit upwards ,that should work it worked on my 99.eldo

Have you actually checked for power at the driver's master switch?
I don't think there would be a window relay, there is probably a power window circuit breaker in the instrument panel fuse box.
If no windows work, pull the master switch out and check for one hot wire with key on. If none, check for broken wires in driver's door opening. Your ground for the windows will be in that group of wires too. Both must work for windows to operate. If you have power and good ground at the master switch, and no windows work, probably a bad master switch.

I am assuming its the drivers door window you are speaking of....
The drivers door has the master window switch w/lockout. The entire assembly must be replaced. The individual switches on the drivers door can't be replaced by themselves. Some GM vehicles allow the panel with the switch assembly to be removed without removing the door panel. However, most require the door panel to be removed for access to the window switch assembly. The master door/window switch assembly is not cheap, by the way.
I would check/replace the window relay first. Usually located under the dash, or under one of the seats.
Might just be the window motor on the problem window.

A mechanic would check for voltage at the switch.

Drivers door switches likely bad.

Have you unhooked the battery since you put the freon in? If not, do it.

check to see if you have power to the window motor.. if so then the window motor is bad, if not the switch is bad...good luck keith...

. Windows use a circuit braker, not a fuse. I wiuld first remove l
L/F door window switch and test for power at switch plug with a 12V test light. Depending on results would determine my next move.

IT SOUNDS LIKE YOU HAVE A LOOSE OE BROKEN GROUND IN THE HEADLIGHT CIRCUIT.

start with a fuse, then go on to a turn signal relay. turn the level left or right on the steering column with the inginition switch on, if the light in the dash lights up but won't flash, it is the turn signal relay.
