Hello all, I guess I must come out of my lurking to get some help with a problem on my 1985 Mustang GT. My car was parked for about 3 weeks, outside in the midwest heat. Since returning from my trip, when turning to the right, I get cold water (or some water looking cold liquid) dumping out the feet vent. Any ideas? I never had this problem before the car was parked. Also, I am not sure whether this is related or not but over the last year or so, sometimes when I turn the A/C on, the temp rises quite a bit. It will basically rise and rise till it gets close to the "Hot" setting at which point I turn it off. Then the temp will slowly drop down to a normal operating temp. What gives?
It's your AC drain. Look by the firewall in the engine bay on the passenger side you';; see a small spout by the bottom. Blow some air or water and it should in clog. If not remove the cabin air filter and try to clean it from the inside.
Who>till it gets close to the "Hot" setting at which
Whoops..
Sorry. Read to fast. I was thinking the air from the ducts was getting hot, rather than cold... not the engine temp was getting hot.
First, do realize that the "condenser" for the A/C is in front of your radiator and when your A/C is on the air passing over the radiator is already warmed by it. Mustangs not being known for exceptional cooling systems anyway are put into overdrive to try and keep the motor cool when things are marginal and the A/C is on. If you're up for it, start from scratch and flush your cooling system and replace the coolant. Make sure the radiator cap is functioing properly (it is supposed to keep a certain pressure on the coolant. It won't keep the temp down but can help keep the coolant from boiling over). Be sure the fan is functioning. An uncooperative theromstat can contribute to the heating problem.
The unit under the dash that warm air is passed thru (the opposite of a heater core) is called an evaporator/dryer. It will sometimes have an amount of liquid from condensation dripping from it and it will collect up and out the drain tube. It's been awhile since I've messed with auto A/C but the most recent vehicle and my Merc Cougar both had drain tubes that allowed the condensation to escape outside the car rather than inside. I can't say for sure where your drain tube exits.
Make sure air is passing ok, over all the systems that are involved. You'll have a hard time telling but be sure that the evaporator is not icing up. I have a house A/C unit that does this when it's on "full blast".
Not like it'll help but... my V6 BroncoII always got to hot with the A/C on... cure? Don't turn the A/C on !! :)
