Where is the ac drain tube for 2004 grand prix
Uhh, maybe try the dipstick tube
It should be on the passanger side fire wall, you should be able to see it from under the car. Hope this helps
Look for it.
under right side of the brake booster
At the bottom of the firewall on the passenger side
Just the drain tube "yes" but not the nipple that it goes to.............
The air conditioner drain condensate tube is located under the hood by the heater core . Remove the tube and clean the adapter, it may have picked up road debris.
back side of motor passenger side car behind belt and down...
There is no drain plug but a condensation drain tube located on the passenger side firewall or just below ( rubber tube sticking out ) It may be plugged and a coat hanger or compressed air will open it. Your heater core may also be leaking if there is also coolant on the floorboard. If so it will need to be replaced.
The condensation drain tube is plugged with crud.
The mass air flow is located inside the intake tube. there is a largish black plastic box on the right side of the engine. It connects to a black tube, there should be a bundle of 2-4 wires coming out if the tube connected to the sensor. This is the setup on my 98 and my 2000 grand prix's both with the 3800 ones supercharged and one is not. Not sure if your year is different but i assume they are the same
You can insert a suction devise down to dipstick tube.
