passenger footwell heat always on - any ideas?

[andyt11]

Just picked up my first porsche (will post pics once we make it home) and the passenger footwell heat is on no matter what we do. Is there an easy fix (1800 mile drive ahead of us) or should I just wrap the outlet in foil and electrical tape and close it off that way?

Everything else is awesome. It will be a miracle if I have a license when I get back home. Sounds good at 6000 rpm!

Heater flapper box is stuck closed, probably a rusted/broken control cable. Just jack the rear of the car up and look just adjacent to the rear shocks. There is one on each side and it looks like this how to tunr off the hot air

Yup. flapper is stuck, reminds me of my old Beetle, no matter how hard you tried you would suffocate, gotta get underneath and clean them, and then lubricate them for the next 30 years.......you are obligated as a porsche owner.

hello andyt11,

you're in Central Canada?

Leave 'em stuck open.

Just kidding. Welcome to the site. Can't wait to see the car...

Check the condition of the cable guide sleeve where it enters the valve. If it is perished it can affect the opening/closing of the valve. The pic in Justin's link will give you the perfect view of the valve and its corresponding parts.

I just replaced my guide tubes to fix the same problem you are having. If this is the case order the part from the host - it's very easy to replace as long as you have some floor jacks or similar and can secure the car well enough to get underneath it!

i used to have the flapper box sticky and could not get it full open or full close. a little change in the cable angle at the flapper box resolved the stickiness.
