V8 Ghia Mike

Hello and thanks for the warm welcome!

OK, a tricky one for you guys. Maybe Mr Herrod can offer some tips? :s5

Two years back I had the 5.0 in my Ghia rebuilt to basically standard spec, except for a balance, ChipTorque custom chip and a mild Crane camshaft.

Now, the CC works OK, in auto and manual modes and isn't showing any fault codes. But the airflow cannot be switched from 'floor' to 'screen' etc. etc. I can hear the system trying to alter the airflow path (so the blend door is getting power), but it remains on centre vents only. I have checked all vacuum lines from the motor and all appears well. The fact that it only started to occur after the engine-out is too much of a coincidence!

Any ideas? Is the system vacuum or electrically adjusted? I understand that cam changes can affect brakes under low RPM, but is my CC sensitive enough to be affected by a mild bumpstick?

Cheers, Mike

does your fresh/resirc work??? if so then your vacuum is ok. You climate control might just need a reset....

Thanks Jase, but the fresh/recirc DOES work! It's just that I can't alter which vents the air gets directed to. Bit tricky trying to quickly demist the screen....

I have tried the system reset option, but no joy there. No fault codes pop up either. Still open to suggestions guys!

Sounds to me that it has a vacum problem,check that the main black vacum hose thrugh to the heater box is not crimped anywere,also the main vacum distributor that is behind the glove box is getting full vacum,if it is the distributor may be faulty

Thanks Rob! I have tried checking the lines before, but may have to really open up the dash/console to get a better look. The fact that it started happening after the engine-out leads me to believe its a hose problem.

It could even be a bit of crud or water in the vac lines. The car was 2 months (!) with the motor out .

One dealer did mention that he sold lots of motors which drive the vent-direction system. Is it partly electrical or all vacuum operated?

Thanks Rob, love your work!

Oh yeah, saw you at the Adelaide 500, climbing out of the big black beast F250 to get stickers from the scantily clad ladies....
