Hi guys ~ I noticed a leak in the interior on the front passenger side dripping down from somewhere in the dash when the A/C is on. I just noticed it. It doesn't appear to leak when the A/C is off.

I have a 92' RR Classic 3.9.

Any ideas?

 

Is it just water or is it coolant? If its water, the evaporator drain holes could be plugged up. If its coolant, then your heater core o rings have been compromised.

 

It's just water.

 

Get under the vehicle and look for the rubber drain ports in the floorboard. One on the d/s and one on the p/s. (right about where your leak is) Take a coat hanger or a wire and clean them out. Be prepared to get a face full of water.
