How do I locate the air conditioner drain plug in a 2003 Honda Element

They are not always easy to see and they differ in length but yes they are typically on the passenger side firewall and may extend down towards the lower firewall or just drop out an inch from the firewall. a coat hanger is not always going to work and you will need to be careful not to put a hole in the evaporator that sits just inside from where that drain comes out. it is possible that the lower cover where the condensation is collected has a crack and may not be pluged at all. look above where it drips on the floor and see if there is any sign of damage to that cover. You may find that it is easier to take off the cover and clean. that will just depend on your confidence in dismanteling that part of the dash and heater box.

this means that your a/c has a leak somewhere in it....or the a/c compressor has gone bad.....you can check the a/c charge with a guage you can pick up at your local automotive store. if the charge is good then chances are that your a/c compressor is bad....kindof a costly fix.

You need to open the sunroof fully and locate the small drain holes at each corner. They will be blocked with debris. Get a piece of welding wire or the likes and carefully unblock the hose by prodding and pouring water down it. When cleared the water shout run away freely.

I ad this problem fixed and it cost $35. Apparently, this happens when the Freon level is low for some reason. They refilled the Freon and now I have AC on both sides. Don't forget to replace the internal filter in the glove box.

This is a common problem when the AC system has a low charge.
If this is the case, you have a leak somewhere. Do not try to fix it yourself without the proper equipment.
