Hey guys I got a 96 and just recently I noticed that I have water dripping on the passenger side floorboard. It looks like it's comming from under the dash. It only drips when the AC is on. Could it be just a line getting condensation on it and dripping? I know the Heat-AC lilnes run right through the firewall right there. I know this really isn't enough information to give a proper diagnosis but any help would be appreciated.
Thanks

 

Most likely your drain is clogged. Look under the hood for a rubber line on your firewall sticking out about an inch. Bet you will find it either gone, or a mud dobber used it for a nest. Probably will be able to run a little something up it and fix your drip.

 

Try taking a shop vac and put the hose over the drain. That should suck the crap out.

I looked the whole firewall over, I didn't see any rubber hose that could be a vent tube or any hole that could have had a hose on it. I only saw two hoses comming out of the firewall on that side and both run into a black bottle.

 

OK, your very close. Directly underneath the bottom of the "black bottle", reach under and you will find it. If yours if 4x4, it may be easier to see it from the bottom. It should stick out about 1 inch and will be about 1/2 inch diameter.
