I recently noticed a leak by the passenger side front tire. I tried to find where it's coming from but can't right now (its dark out) its leaking an oily substance, It's like extremely watery oil. lol thats the best way I can describe it. Any ideas?

I have been using my defroster a lot lately and I know thats where the HVAC leaks or whatever.

 

Check heater hoses
put pressure tester loan a tool part #9300 at autozone on where radiator cap goes it will pee out where ever it is leaking
