See my profile, Have you been using your A/C or Defrost alot?
If you have, condensate forms on your evaporator (sorta a radiator looking A/C thingee in your heater box!)
Eventually, it forms bigger water drops, and falls into the bottom of your heater box.
The water can only escape one way. The CONDENSATE DRAIN!
IT MAY BE STOPPED UP!
Since I do not know the technicals of your rig, I can tell you sorta where to look.
Look on your firewall, maybe low, get an idea of where the bottom of the heater box is. Look at same height on the firewall. Probably Center or towards the passenger side.
I didn't say this would be real EZ!
Maybe look for some/ or not, dampness around a rubber apperattus (sp) or rubber tube. When you locate it, do one of the following:
Poke something in it, make water flow out. Sometimes a bad Idea.
"Why", you say, in an indignant manner.
"Been there done that", CJ MEDEVAC says, and continues, without using quotations!
If you poke it, You shove the blockage back in, you'll be doing this unstopping over and over.
Found 2 ways to do this well, Using a rubber hose and/ or 1/4---3/8 copper tubing.
Dependent upon the accessibilty to the drain in a tight spot, you might have to bend the tubing and do some "Fishing" to get it into the condensate drain tube. (JUST INTO THE END--MAYBE 1/4 to 1/2 Inch)
Once this task is achieved (or figured out), Rig the tubing and or combo with rubber hose, into the hose of your "Shop-Vac". Using Duct Tape or Other, seal it all together. So that the vac efficiently can suck the hose/ tubing with no vacuum (suction) leaks
You already know what to do next. DO IT!
Suction out the drain tube. So that you draw the stoppage into the vac. Along with all of the water. And any other potential. Later on stoppages. (In other words, once it starts draining on its own. Do Not Let It. Suck it until empty!)
Keep in mind, we are not performing heater box orthoscopic surgery, do not shove it (hose or tube)past the firewall, you may tear or diconnect the drain. Me can't helpy you then!
Sometimes there is alot of water!
Please let me know if my method worked for you (OR NOT), and did I explain the procedure well enough?
