Respect for buying the CF wheels. I’ll be interested to see how you get on with them, the look is great and I’m interested in how durable they...
Yes, I need to check the pump and understand the interface from the ECU to the rest of the car. When the motorised valve failed, I took it apart...
Thank you. So far, we've discovered the temperature control is nothing more than a switch which provides an increasing resistance to ground as the...
Thank you, those match my own measurements exactly, within the tolerance of the resistors! If you now measure the voltage at Pin 5 with the...
Yes, the motorised valve was replaced by the dealer at a time when it was no longer available as an OEM part with a fix package using a...
No problem then! As for 2k48, you’re right, this is standard shorthand notation for resistance and capacitance values, you just need to know...
Yes, at least it’s only two layer… Qavion, any chance you could repeat your resistance measurements between pin 5 and ground as the temperature...
[ATTACH] Here is the schematic of the HVAC controls. For simplicity, I'm only showing one of the push buttons and its light, the two are...
[ATTACH] Here is a closeup of the temperature control switch and the 10 resistors which it uses to create a resistance which varies by setting...
From what I’ve found out, the most important resistance values are those to ground, resistances to the positive power are in effect going through...
An update. My car is now back from its rather expensive service - £12000, $15000 and I've had the chance to trace out the schematic of the HVAC...
Yes, the gauges come out with the surround. Each gauge is attached with two screws into spigots moulded into the panel. If you have removed the 6...
Yes, thanks for the resistance measurements, I will make the same when I get it back. Was your panel working when you made the meaurements? It's...
It turns out my car, which is 28 years old needs quite a lot of work to fix oil weeps, sagging engine mounts, a noisy water pump and, and, and, so...
Thanks, the dealer has swapped the panel for a known good one and the problems (no heat and incorrect air distribution) have gone away. This...
My dealer tells me my aircon control panel is faulty and that a replacement from Ferrari costs $3000. It has three controls (temperature, fan...
Thank you. My aircon was fixed to replace the motorised control valve and it’s obvious they had the HVAC control panel apart for whatever reason....
Question for F355 owners. Does the aircon circulation button light up green when you press it? My recirculation flap is no longer responding to...
I’ve ordered my 296 GTS in Sanu Silver, red and black interior, Daytona stripes. The silver really pops in the sunshine.
Here in the UK, a base GTB is $296k, a base GTS is $345k including taxes. The car has hiked in price significantly, the GTS more so but there are...
