740 leak issue

Reubo

Hello All I have had a leak in the passenger side footwell of my ‘87 740 turbo leaving water under the carpets.
After removing carpet and other material I have located the area the water is coming from with a hose. I pointed this out in the photo.

Does anyone know what would cause this and how to fix it? Image description

Reubo That 'hose' sits right below the condenser for the air conditioning. When the AC condenser gets cold, it will shed condensate (water) from its fins and that is meant to drain out that tube, the other end of which appears in the engine bay.

If you're getting water leaks there, you may need to look at the condition of the seal on that drain between the inside and outside of the firewall. It's not easy to find the outlet on the engine bay side, since it's directly below the inlet and outlet pipes for the condenser, etc.

How's the drains in the cowling behind the wiper panel?

Reubo

Sorry ramrod I’m not too familiar with the lingo or parts of the car, is that the grill between the window and wiper blades?

Reubo

Oh I see, but will that cause rain water to get into the car? Because the AC hasn’t been used for a long time, it’s just outside water getting inside.

Reubo Does you get water inside the car after driving in the rain? If so, water may be getting in when road spray is making its way onto the firewall.

Or are you getting water in the car while it's parked and stationary? If so, that drain hole for the AC condenser may not be the source of the leak, and you'll need to look at the drain for the blower motor (which appears to have been removed, going by your picture).

Im in the process of fixing up the car, so it’s just been stationary mainly. I haven’t driven it when it’s wet out

I’ve just done some more testing with water and I believe it might be coming through this seam between the wheel well and the car. Does anyone know if this could be the issue or had something similar?
