My cooling fans on my 99 are not running and won't cool the car. Any suggestions would be greatly appreciated.

You can guess then buy new parts on a trial-and-error basis or...
...you can purchase a set of Factory Service Manuals and use the cooling fan diagnosis instructions to decide if the problem is the fans, the relays, the wiring, the connectors or the VCM.

Or you could save yourself the cost of the manuals and just go out and pull a relay and look for signs of overheating.

BINGO. The second smartest thing to do is learn how to pull your codes..

First you suggest that the OP change the fan motors on his ride without knowing anything about the mileage on his car, any modification or recent repairs that may have caused the problem or what codes the car may be throwing. The fans on this car are not notorious for building up any kind of resistance and slowing down. The radiator will need replacing way before then. I'm coming up on 150,000 and my car runs cool as a cucumber. Second, you suggest he save himself the cost of the service manual. Not very solid advice given the service manual was written by the guys who designed the car from the ground up.
This ain't no Impala we're talking about here.
To the OP (if you are still experiencing this issue), start by pulling your codes. When trouble-shooting this car, you don't turn 1 bolt without seeing what the car is trying to tell you. Like Hib, I'm going to highly suggest you buy the service manuals for this car if you plan to work on it. There's nothing more frustrating (and frankly, stupid), than working blind. When you pull the codes, you are going to be looking for DTC's 0480 and 0481 in particular. Also, check MaxiFuses 48 and 49, along with MiniFuse 14. There's also Mini Relay's 43, 44, and 45 which play into the equation so they will also need to be checked.
Work smart my friend. Arm yourself with the necessary tools and information to be successful.
