not 100% , generaly the heater core in most cases but should be hot and the colour of the radiater water. I do recall my air con guru say their is a aircon part under the dash but does it leak? It should be clean and not hot im guessing. Does it release water under the car as it should, or is it blocked.

Check that the drain pipe is clear and still connected to the trans tunnel

Yep x2 its probably a blocked drain tube.

Clean the evaporator drain line with a wire tie until it drains freely. Don't use a screwdriver , piece of wire or anything hard to clean it because if you hole the evaporator replacing it professionally will cost more than the car's retail sale price.

Someone, not me, has drilled a finger size hole in the side of the heater box on the passenger side right down near the bottom. It's plugged with a tapered cork so it doesn't blow air during general use. With the plug out ` vDeedI can reach in with a finger and feel the top of the drain hole and feed a large cable tie DOWN the drain tube. A good mod. Much easier than doing it from below.
A `blocked drain tube is the likely cause of the OP's problem.HOWEVER, if tempted to drill an access hole as above, I recommend ensuring the heater box is drained FIRST. A week or 2 ago I noticed some water in the footwell after a drive and pulled the plug to clear the drain and about a litre of water gushed out into the passenger side footwell. That wouldn't be a good mix with an electric drill.

I have an idea the side hole is a standard feature on the VP - VS. IIRC i blocked mine off with sealant as the bung was missing.

Hey Losh, you may be right but the hole is a bit rough looking. A wobbly circle so I assumed it wasn't factory. I've seen a few posts describing how to clear the drain from under the car too.
I made a bung by shaving down a cork from a wine bottle. Hard to get these days unless you've got a cellar of old wine or drink imported
