i just noticed that behind the passenger side wheel on the frame there is some fluid dripping, it looks like water with no distinct smell. any ideas on how to approach this?

 

that is water coming from your a/c evaporator drain. it is supposed to be like that.

even though i never use the a/c. and i mean never.

 

if you use the defroster. then it use's the a/c system aswell.

 

water not coolant?
agree location of fluid is typical condensation area.... vehicle has a/c ?
defrost setting engages compressor...might want to confirm ac compressor is not engaged..

where do you live without needing A/C in august??

 

haha, well kansas. i just roll down the windows and pop the back two and the sliding rear. i rarely ever use the thermostat. i guess i did use the defrost this morning.

 

I just purchased a '98 and I've noticed an accumulation of moisture on the passenger floor after running the A/C for a long time.

Any clue as to how this is happening?

 

I just fixed this problem in my truck. where the evaperator drain goes through the firewall there it like a small foam gasket that sucks. it leaked bad in my truck. so i pulled out the seats, and carpet. and got some black rtv silicone and siliconed all the way around the evaporator drain goes through the firewall and let it set up and but it all back together after thorgholy cleaning the carpet, so it didnt rot and smell. and after my road trip from school to home (1500 miles) and using the a/c the enitire time i did not see anymore water building up. you could pay someone to do this or spend 2 bucks on silicone and spend a couple hours and do it yourself.

 

you might also check that your AC drain isnt clogged up.
