Question about 1993 GMC Suburban

2 Answers

Air conditioning When on a long trip the a/c drips water inside the cabin. It also stops blowing cold air and it seems the air flos switches to the floor vents. I can turn the a/c off for a few minutes and it will again blow cold air and work ok for awhile. My question is could the condensor be freezing and causing the housing to sweat? Or is there some other answer? Around town and on short trips it works fine.

Yes. You need to clean you coil. I is also posible that you are low on freon.

How do I replace the cabin air filter?


Cabin Air Filters are usually located behind the passenger glove compartment. Remove that and you should find your cabin air filter.

Why does my heat blow warm air then it turns cold


its VERY likely that your heater core is getting stopped up.

The heater in your car works by circulating hot water from the engine into a copper or aluminum pipe coiled up in the dashboard. The heater/airconditioner's fan blows across it and the hot air comes out of the vents. This is why the heater doesn't work right away when you first start the car. It usually won't work until the hot/cold needle in the gauges is starting to rise up.

If your mechanic recently replaced the thermostat, its possible that there is air in the system which will result in less antifreeze in the car than it should be. If this is not the case, the heater core is probably stopping up and will require expensive replacement if it cannot be flushed clean.

Check to make sure the car is full of antifreeze IN THE RADIATOR, AND THE OVERFLOW JUG. Please be very sure there is NO AIR in the cooling system as well.

What makes a/c system blows white smokelike out of vents


What you are seeing is probably fog which is a large amount of water in the evap box. Some times the evaporator freezes up due to a lack of air flow or a restriction in the flow of freon in the system. The floor drain could also be stopped up and not letting the water drain out of the car.
You can check to see if a puddle of water is present when the car is parked and the a/c is on. Also try switching from fresh to recirc and see if it makes any difference on air flow. You may have a restricted cabin air filter too.

Air condition wather in the interior car


Could be the drain tube is partially clogged. It is usually located on the fire-wall or down towards the floor pan under the car. It is usually close to where the A/C lines go thru the fire-wall. About 1/2 inch diameter sticking straight out but may have a 90 degree elbow pointing down.
Also, it's been extra hot and humid all over and moisture could be freezing inside the unit when on MAX A/C, then suddenly melting when switched to normal. This opens the outside air door and allows warm/hot air into the unit instead of recirculating the cold air inside the car. The drain may not be able to handle a large, sudden quantity of water.
Perform a "driveway" test. Open the hood, start engine and run the A/C on normal with the windows or doors open. Locate the drain tube by looking for water dripping. Once located twist 2 or 3 pipe cleaners together and verify the tube is clean. Then close the doors/windows and switch to MAX A/C. Check for water dripping. If it stops dripping, water is freezing inside and now you know why!

My heater isn't blowing cold but my cold air conditioning is working. It does blow, just not warm. You may need to know that I recently had my radiator and water pump replaced. I had hoped these problems...


May have to 'flush' out the system, especially if the heater core has 2 hoses at the 'firewall' that are not getting hot when the engine is hot.

If the hoses are getting hot but it's cold inside the cabin, then it's a bad blend door actuator problem.

Good luck on this repair.

Dropping water


Are you loosing water from the inside of the radiator?...then it is a blown head gasket, or a cracked head/block. Is there steam coming out of the exhaust? Is the water dripping from the exhaust pipe and from the small factory hole in the muffler....then it is normal. Most likely, as every car with air conditioning, the evaporator core collects frost even in the summer and the A/C cycles to heat it, and melt it off. It is meant to drip through a small pipe, under the car, onto the ground. It is perfectly clear and clean water. It is normal functioning of the air conditioning. In the winter when the defrost is selected to clear the windshield, the automatic air conditioning produces cold dry air, which is then heated to clear the moisture. Frost collects on the evaporator core. The system cycles to heat it off from time to time and it will drip clear water in the winter when you didn't even know that the air conditioning was on. After all who needs air conditioning in the winter when you did not select it. The automatic system turned it on to dry the re-heated air to clear the moisture from inside the car.

2005 Chrysler Pacifica-Air conditioning leak


The 05/04 Pacifica did not come with an elbow tube on the drain line for the AC drip pan. As you drive, the air flow into the tube pushes the condensate water back into the pan which is inside above the passenger floor board, the drain line is under the hood on the firewall. I spoke with the parts guy at the local Chrysler dealer, he sold me a drain tube for the 06 (~$10) and I installed it, wasn't too hard to do from the top if the engine is cold. The elbow slips on over the drain tube. Make sure to point the tube down. It only took one trip to start seeing water drip out of the tube and the floorboard started to dry up and almost three years later, the floorboard is still dry.

1994 Previa A/C problem


Look to see that the A/C condensate drains are working. You should see water dripping out from the front & the back whilst the A/C is running. If no water; clean the drain tubes. Also, you need to be running the A/C on the RECIRC mode (the little car with an arrow doing a u-turn inside the car); if not, you are air conditioning outside air, and the unit is icing up from too much humidity. Sort of like running your fridge with the door open...
If neither of those items correct your issue, you may need to replace the A/C thermister; but, that is a very rare failure.

I have a 2000 dodge ram 1500. The air conditioner blows just warm air. The system was working when engine was shut off but did not work properly upon restart today. The AC/Max A/C switch seems to work...


If the compressor is outputting cold freon maybe the vent in the dash is not opening to allow the air to flow thru the condenser. Try operating the heat/cool switch and the recirculting air control in an effort to get it to open the damper.
