Air Conditioner Drain Clogging Up

Hi, on 09/01 you mentioned to someone that their air conditioner drain might be clogging up & dripping on their ECU, thus frying it up. This has indeed happened to me.

Do you know how to get the drain fixed up again?

I don't want to put another ECU in there to have it fried by the same problem!

You will need to pull the evaporator box out of the car and remove what ever is in there at the drain tube clogging it up. It could be bunch of pine needles or it could be mouse nest stuff in there causing the clogg. You will not know until you take it out. Or instaed of taking it apart, blow compressed air into the drain here and there to keep it open. But that's no garantee way of doing this. Take it apart would be the right way. You could install some kind of a screen on the car air intake which is below the wiper cowling, to prevent mouse from getting into the air duct system and I would also check inside the blower motor housing for any debriss inside of there. So good amount of work if you want to get this done right. Good luck.

Air conditioner leaking in passanger floor boards how do i fix it

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, its 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!

Air conditioner condensation dripping into the floor.

Check the drain hose, chances are it came loose from the fitting on the AC unit. Make sure the hose goes through the floor board.

Air conditioner is working in my 2007 edge but water dripping from dashboard and when I turn you can hear water moving around from behind the dash.

Check the drain hoses. If you are getting water inside the cabin, namely on the passenger side, then you have a clogged or crimped drain hose.

Feel around the passenger side front foot well for wet carpet. Inspect all the hoses and drain plugs to make sure you remove the clog.

1990 toyota camry air conditioner leak on gas pedal

If water is dripping on your pedal the condenser drain is probably clogged and is not draining outside. Check along the firewall for the drain. It will be a rubber tube with a closed end. Pinch the end and there is probably dirt etc. clogging the end. You can cut the tip off and you'll never have this problem again. You can also run the A/C and see if you see a puddle on the ground. You probably will not see one.

There is water dripping on my foot when my foot is on the gas pedal this has just started what can this be?

It could be that the drain that removes water when the a/c evaporator drips is plugged and it is backing up into the passenger compartment.

If it happens when it rains it could be a leaky windshield or water leaking in through the cabin air filter.
