Thanks all, I will have a look this morning under the car.

 

Got it fix the drain box was blocked. I've got a nice shower under the car.
For your info the drain box is near the exhaus under the car.

Thanks all of you for your help.

 

that happened to my car along time ago too. i guess it was blocked some where from dirt and stuff but it must have unpluged it self from the dirt cos it doesnt do that anymore.

 

When I bought this car used the heater core was bypassed and I could see from underneath that there was obviously a leak into the passenger compartment.(Rust) Naturally I put 2 and 2 together, replaced the core, put it all back together and it started leaking again, but only when the a/c was on. There is a seam in the bottom of the drip pan that is leaking condensation into the passenger compartment that I can only assume was originally caused by the leaky heater core.

Its a real &^%$# to get to but I think I can pour in some epoxy to stop the leak.

 

Be sure you check all your rubber seals for leaks, especially if you have T-Tops...

 

Go back and read this thread from the beginning, and what the fix was. Your A/C condensation isn't draining, meaning.....a clogged drain hole. Epoxying something isn't going to stop the water build up, it needs to get out.
