Whats the diagnosis DR's?

The AC works off and ON.. The heat works fine, but it'll fog up the windows from the inside.. LIke its blowing out moist heat.

I ebliev it's the thing under the dash, but for the life of me I cant think of whats its called. Its had to be replaced on my truck and my mustang (in the past)..But, the name is at loss to me.

 

AHA!

The heater core. Thats what I was thinking of. Also, could it be the evaporator is clogged up? Thus why water drips when the AC is on?

And coudl that be the culprit w/my windows fogging up as well?

 

nothing?

THats what happened with mine. THe drain hose that goes through the firewall was kinked on mine after working on the evaporator. Either that or there is something clogging the hose. Make sure the hose is not kinked and there is no leaves or anything like that in there. you can use a coat hanger

 

clear the drain passenger side of the car under firewall

 

the previous guy is right, it could be you line clogged

or

it could be your expansion valve has gone bad. that happened a long time ago to my old accord. does your idle surge at all? when the AC clicks on does your idle drop a lot more than it normally did in the past?

 

hmmn.. i dunno abotu the idle ropping. its been messing up for so long I cant remember. I"ll pay more attention to it.

and thanks for the tip on the water draining.. I"ll fix that this weekend.

Now, what about the heat fogging up the windows? why woudl it be doin that?

 

well your windows are fogging because your AC is not coniditoning the air...the purpose of the ac is to turn the warm damp air into dehumidified colder air. if your AC isn't working properly, that warm damp air will fog up your windows...that why im leaning more towards your expansion valve might be shot. mine started to do that recently, i think i need to have my system recharged since i've got 170k miles.

 

No, your windows are fogging up because the drain is clogged. If there's a pile of water in the ventilation ducts, your heater will produce very humid air.

When it blows moist air, does it smell like anti-freeze? If not, then your heater core isn't leaking.

Fix the drain first, then worry about the rest. I bet your moisture problem will be solved after you clear the drain. Don't worry about your AC until after you clear the drain first.

Not sure about your year, but look for the ventilation ducts coming down to a low point way forward in the passenger footwell. Look for a rubber hose from there going thru the firewall...
