Dumb question here that I am sure you all know the answer to...can anyone tell me exactly where the AC drain tube is on my '85 Delta 88? Getting some water on the pass side carpet and want to check to see if tube is clogged.

 

Here ya go...

Not dumb at all, esp. since there is no actual tube...

Is that water coolant to indicate the heater core is leaking?

 

Thanks, Rob. Great info (even though it will apparently be a massive PITA!)

Not sure I understood your question about water coolant?

 

I think it's just plain water from the AC. Unless there is a water leak from the outside, but the location of dampness would seem to indicate AC.

 

Anyone else ever have this issue? Both myself and mechanic have come up short figuring out how to check to see if the ac is clogged.

I did look at the other thread but since 442b is the guy I bought the car from I guess he didn't figure it out either!

 

he's asking as that is also the place coolant will leak if the heater core goes bad.

 

Thanks, I realized that and answered in my next reply. I don't think it's coolant.

 

You would need to get the car on ramps and probe open that flap thats deep up in there to see if tree debris is in there. The cowl itself drains through the evap box, so any tears int he screen can let big stuff in with can cause clogs.

 

I appreciate the response. The problem is that nobody can see this flap. The car was up on a lift today.
