It's under the right side dash near the transmission humo. Mine leaked for who knows how long and I had to strip most of the carpet out and dry it for 4 days with fans. The idiots that built the car slipped the drain hose on the plastic pipe but NO CLAMP so my morning rider to work had his big feet up there and knocked it loose. What a mess. If yours leaked, get it bone dry under that carpet of it will stink and rust the floor pans. Just put a hose clamp on it and that will prevent the big leak.
The 2003 Pontiac Montana air conditioning compressor condensation drain begins on the bottom of the air conditioner compressor. The drain goes from the compressor to the bottom of the engine compartment.
Yes, there is an air conditioning relay on the 2001 Pontiac Grand Prix. The air conditioning relay is located in the fuse box underneath the hood.

I changed out the blower fan on my 89 without having to remove any of the a.c. The fan housing is against the firewall in the engine compartment. There is a two-wire connector going to it and a small rubber hose for condensation drainage
There are two valves on the air conditioner on a 2000 Pontiac Bonneville. Attach the hose that fits the refrigerant and fill that side.
You may need to charge your a/c with coolant.
