Where is the a/c drain line on a 95 Grand Prix SE

It's not water ? That's the drain for the A/C evaporator core . When you use your A/C it takes moisture out of the air an drains out of that drain . If it's anti freeze your heater core is leaking ,but that usually ends up on the passenger side floor an fogs up the inside of the windshield .

Remove top cover over radiator and then upper bracket bolts, drain system and disconnect hoses and cooler lines from ****** (may need special tool) and the radiator just lifts out.

your air conditioning drain is probably stopped up.the drain is located on the passenger side along the firewall.

There is a drain line on the firewall that is plugged.
Had the same problem, unplugged the line and problem solved.

put the key in trun it on do not try and start it just trun it on. leave it on of 20 min.s then trun key off and try to start this should reset the computor.

Your AC drain is clogged. If you look near the floor under the dash on the passenger side you will find a small rubber hose that goes thru the floor board. Take the hose off and clean it out. You will find that it is clogged with dirt. Once it is cleaned out hook it back up under the dash. You will notice that if the car is running with the AC on, you will be able to see water dripping on the passenger side under the car that will mean you cleaned the hose out and it is working.

maybe a water pump.

Check the bottom of the door for clogged drain holes. Could also be a weatherstrip seal leak around the door opening. Worst case there could be a leak around the windshield gasket.

Sounds like your A/C drain tube is blocked. You will need to get it blown out.

Under the passenger side of the vehicle, near where your feet are, should be a drain tube. This get clogged from time to time by road grime and usually insects, so carefully use a small screwdriver to clean it out. If this clogs, the A/C system cannot remove its own condensation and it backs up into the car.
