2006 Jeep Wrangler A/C Condensating into floor


Air Conditioning problem
2006 Jeep Wrangler 6 cyl Four Wheel Drive Automatic 40000 miles

Can you tell me what can cause a extreme condinsation in the passenger side floorboard. A\C seems to be working fine but it builds water up all over the outside of evaporator box.

Do you
have the same problem?

See my profile, I answer alot of the CJ 5&7 forum questions.....I am a member like you...not a paid mechanic.....This is my Hobby!.....They upped me to helper status 'cause I can assist on some repair issues

I cannot be sure, but it sounds like your EVAPORATOR/HEATER BOX may be full of water.....usually when this happens, on vehicles I am familiar with........turning a corner will slosh water inside of your cockpit!

So the thing to do is see if you are producing water and it is dripping on the ground or driveway....maybe its not dripping out fast enough!

The way to Test/Fix/recon/eliminate this possiblity is take a SHOP-VAC (size no matter) and using Duct Tape or other, REDUCE the size of your vacuum inlet, by taping on a "SMALL GADGET"

This gadget may vary, depending on how much room you have or what you must go around.

On my Dad's T-Bird, I had to use 3/8 copper tubing, 3 feet long, bent 2 different directions to get to my OBJECTIVE!........You might get by with a Hollow Ink Pen Body (I do not know your set-up)

What you want to do is Place your Gadget in the Rubber Drain on the engine side of the firewall (probably just opposite of your sweating evaporator box) If it drips some, it should be EZ to find.

Next, crank up the vac!

Now I know you are wondering why I did not tell you the EZ way?

1) If you just JAB it free, you just SHOVED the crap stopping you up.......BACK IN!......Be doing it again real soon!........Been....There, .....Done.....That!

2) Neighbor did the JABBING THING (cause I was an idiot, when I told him, what I told you).......Seems he got a constant wet floorboard afterward.........He TORE his rubber drain inside of his rig, behind the heater!

3) If you Jab deep with your gadget.......you might be boarding Ron's little boat!........Just put in far enough to get a good seal....insure your gadget end is large enough to seal the hole, when you crank up the vac!..........what you are doing is sucking out GOO, with the consistancy of SNOT!

Sorry, no other way to explain it

So do you understand the mission?

Do it when your problem is occurring, so the backed up water will wash the drain when you vacuum it!

Now Get To It!

Let me know if it worked well for you.

This is my A/C in the Max Position on "WILLY", my '46 Willys Jeep When we start feeling condensate, we simply shut the windshield! (My other Jeep is a '77 CJ5, No A/C)
