Yep got it, ship to you pp address?

Hi, the regulator is not difficult to install if you are mechanically inclined. I don't think $100 is out of line to install, since it took me a couple of hours..although I probably could do it in an hour now. The $125 to diagnose the problem may be ok depending on how long it took them to figure out what was going on. Hope tha helps.

Hi Derk
I posted this on the forum, as well...

A few years a go you posted the reply (pasted below) related to a 964 ventilation problem. I have a 1991 964, my cockpit fan does not respond at all. The fan blows at low speed only. I had the same problem 6 months ago, and I replaced the regulator and it solved this problem. Unfortunately I replaced it with a used part for a cost of $200 rather than pay the $530 I was quoted for a new regulator.

Questions:
Do you know if this part difficult to install? The repair shop charged me $125 to diagnose the problem and another $100 to install the part -

Let me know what you think and thanks in advance.

Steve

Your post....

I had the same problem. It turns out that the speed of the fans is controlled by the blower final stage amplifier (regulator) located behind the gas tank in the front truck. It accepts a signal from the ccu and adjusts the blower speed based on the input. ..
