New owner of 911 need advice

[Guest]

Took the plunge and got myself a 3.2 carrera, my first 911 and after a coulpe of weeks there are a couple of things I would like to know. My car is a targa and does not leak, but when you get over 80 with the targa in place there is alot of wind noise, is this normal?
The second thing is the car always puts out hot air in the cabin no matter where the levers are, should you be able to shut off the hot air completely as it does get very hot in the cabin, the fan is not working, but will be fixed soon, any help/advice more than welcome
regards
Martin
PS the car is a 1984 3.2

All Targas seem to make this noise, as the fit at the top of the windscreen is not always perfect - no doubt, Targa owners will suitably amend my comments !

The hot air is usually caused by the heater valves in the engine compartment (two, one per side, on the firewall) sticking closed (open means the hot air is returned to the engine compartment). Hot air is forced into the system partly by the engine cooling fan, partly by the heater motor fan in the engine compartment (with another fan in each footwell for extra 'umph'.)

The valves can be 'persuaded' to operate (they rotate open/closed), if you can get at them, but they do tend to rust.

All the problems with extra heat in my 87 3.2 have been down to this problem, including a slight amount of hot air at the moment on the drivers side (which I deflect to the windscreen), but the A/C normally masks this.

My targa is a little noisy on the motorway and I seem to have constant hot air in the cabin!

Solution.

Take the roof off and turn the stereo up[]

hi to you.

you don't say which fan is not working, the one at the back of the car (the heater fan or the one in the luggage bay, the fresh air/ cooling fan).
if its the rear one cheack the fuses, there are some in the enging bay on the left hand side that the fan is wired through.

good luck

Bagpuss,

Welcome to the forum, as John previously said, wind noise is something you have to live with, unless you want to have your targa top refurbished.

After a number of years and miles, it is normal for the body to have "flexed" - therefore needing for the roof panel to be custom fitted. Mine was like yours..noisy but water proof, and although the front an rear seals didnt need replacement, about everything else did!

I chose to budget for the work a year later than the quote, due to the expense...but now
am happy with the results.....work carries out by Southbound Trimmers approx £850.00 inc Vat!

When my Targa roof perished after 25 years service I bought a kit for £70.00 from Southbound (they are normally about £115-125 but they owed me, it contains everything including linings and glue) and a friend and myself made a professional job of completely recovering the roof in five hours. Do it in hot weather if you decide to do it yourself. If the metal runners have seen better days Southbound can supply new ones and they are not expensive. If they are not available recoating is an option. Recovering a Targa top is not difficult if you can follow instructions.

Hi Martin

Silly one to start with, but I assume you've realised that the hot air is also controlled from the dial behind the handbrake lever??

Regarding the Targa top, there are variations in noise. When I first had mine the wind noise was intolerable and I realised that the little clips at the front and back that the folding bars push into were coming undone slowly as I drove along. I solved this with the improved clips available from www.type-911.co.uk. There is still wind noise, but it is tolerable and no worse than your average convertible.
