So I have noticed that there is a strange substance that slowly drips out from under my dash on the passenger side. . It is colorless and odorless (not coolant). . My first thought was that it was condensation dripping off of my air conditioner components in the dash. . I thought this until I ran my finger across the bottom of the dash, like the outside bottom edge of the glove box, and apparently this "unknown substance" gels when it cools down. . Thats right, it has the consistency of say vaseline or hair gel, however it has no odor or color. . I'm not too worried about it because all of my fluid levels are just fine (this has been going on for about 4 months) and everything in the truck works fine. . However, it is really starting to **** me off because I have no earthly clue what it is... please help me identify what this is or the cause of this unknown, colorless, odorless, gel-like substance. . . .

that's where I left my hair gel. sorry buddy.

On a serious note, it could be just adhesive,

 

adhesive for what?

 

Are you sure it's not dexcool? Is it slippery or sticky?

 

dunno, just throwin out ideas

 

It isn't sticky.... it's slick. . . but isn't dexcool redish orange? and if it were leaking fluid, I would be low.... and it would have an odor..... it doesnt though. . . this is what confuses me soooo much..... I think it only drips if the air conditioner is on.... could it maybe be a lubricant for the blower motor on the a/c or heat? if it is a lithium based lube, it would gel like that and not have color or odor..... but I don't know if it could be that, I haven't exactly had my dash apart so I dont know where the blower motor is at. . . oh well, it's not affecting the truck, just annoying me. . . I am 1000000% sure it IS NOT coolant of any form. . . . . . I also know it isn't dexcool, because my radiator and cooling system have been flushed and replaced that junk with prestone 50/50......

 

My next thought would be possibly pag oil from the a/c evapoator core. It's clear and odorless. If it is leaking, then the refrigerant must also be leaking and the a/c would be less efficient. Hard to check when it's cold outside already.
I wonder if you check under the hood if you can tell if there's anything leaking under the evaporater case near the firewall?
