Hi Scotty,

I appreciate your upbeat, informative and fun videos. I own a 1994 Mercury Grand Marquis LS and whenever I run either the heat or AC, I am getting moisture under the passengers side carpet. It's water and not antifreeze. I have already attempted to clear out the evaporator hose underneath the vehicle. What could be causing this and any suggestions for resolving this.

Thank you kindly :-)

well, either the drain hose is clogged inside the evaporator, flush the crap out of it with a garden hose, that often works. Or the evaporator plastic case is cracked and often silicone sealer can fix that. good luck
