Default need some quick AC help on a 94

Where is the drain located on this system? The car is draining water (not colant) into the passengers floor board so I believe that the drain is clogged up. Where is it located at? Thanks for the help.

If it is not coolant, the only other "watery" liquid in your vette is your windshield washer fluid.

Check passenger side behind the front wheel under the car. It is usually under the evaporator. It is probably clogged and thus draining water into the passenger floor. Happened to my old Honda before.

Easy fix...my 94 had the same problem two years ago.

There are 3 small drains under the windsheild ledge...one right, one left, one center :yesnod:

The best way to get at them is from the top. Remove the screens and find the small drain holes. You will have to feel for the one on the passingers side...next run a 4 foot length of weed wacker line down the holes...you will have to attempt this a few times...since your drain holes are clogged :eek:.....if its glogged too bad you can access them from the bottom by jacking up the car, use a flash light and look around by the firewall....the passingerside train tube snakes down by the fan unit and AC condenser box :yesnod:

Once you have the drain tubes clear your floor board will not flood out...hope this helps, Larry :cool:
