Just like the title says...Don't know to much about the A/C system but whenever i have it on for a while condensation forms on some part under the passengers side dash and leaks on my carpet. What do i need to do to fix this? HELP?!

Check the AC vent tube, and make sure it is not plugged up

Where could i find that?

elblako91

I went out to the truck and found the tube. Nothing was coming out of it so i thought it might be plugged up. I wiggled it around a little and it started to leak a little on to the ground. It still leaks though in the cab and i took some pictures. Any ideas??

NicCantDecide

Crack open the evaporator enclosure under the dash (its that thing you took the picture of that's leaking). Its probably flooded with water and when the A/C kicks in it causes more water to condense and flow over.

I'm not exactly sure how that thing opens up, but there's either clips to pop the bottom off or screws/bolts.

See I'm thinking the same thing. I stuck weed eater string up the A/C tube and now it leaks out on the street not inside. I cleaned up the condensation and let the A/C run for 10 min. Thankfully its now draining outside the truck now. I'm not going to mess with it unless it starts happening again.
Thanks for everyones help!

Off topic, but in your sig it says your truck has 5000 original miles? It's a 92? WTF happened?

elblako91

Ha I was waiting till someone would ask me. My Dad bought it new in 92 and used it for about 1-2 years driving to and from work. All highway miles! Went in the garage shortly after and has been in there ever since. I took it out earlier this year because my 1974 chevy nova has had some engine problems so the yota is now my new Daily driver. It's weird. Its like new but old at the same time.

Normally to fix this problem, you would shoot some compressed air up the vent tube and it will start flowing again. If no shop air, a coat hanger would work. Just be careful.

if water was sitting in that box for any length of time you might want to spray some lysol down your cowl to keep any mold or whatnot from growing in there

Just wanted to bring a closure to this thread.

I ended up ripping it apart and sure enough there were leaves and other crap in it. As i was cleaning it i dropped it and broke off the little nipple the hose connects to. DOH! Anyways after some epoxy I put i all back together and no more leaks. YAY!

I hate to bump such an old thread, but I'm currently having this EXACT same problem (I just emptied about a quart of water from under my dash (eek!).

When you unplugged the hole, did you do it from the outside or the inside? I may or may not have access to compressed air, but I know that the tube in the bay is solid metal.

Also, what's the trick to getting the box out (if I have to go that route?) Did you pull the (3) Philips head screws and the 2-3 hex head screws and then drop the box down?

My rubber thing is starting to crack a little from when I disconnected it to drain the box, but I've got some great sealant tape if I need it.

I hate water leaks...

etc.

From under the hood.

You will see 1 small rubber hose sticking out on the pass side... half way down the fire wall. Place unclogging device in hose and waaalaaaa

Whatever you do, don't pull the drain hose off from the firewall, it is nearly impossible to get back on (unless you have a lift)...

etc.

Is this experience talking?

ProjectMcFly

Really?

I pulled off the glovebox and then just loosened all the hardware on the HVAC equipment and pulled it back. I was able to pull off the drain hose and unclog it with air and then just pushed it back in from the top.

I think the fact that I could easily access both sides of the hose made it easy to pull off and reinstall.

Regardless, water now leaks outside the truck and not inside, so that's one problem solved.

Yes, school of hard knocks...
