Ferrari Mailing List: Re: Ferrari Mondial HVAC issue fixed

That’s even better! I picked up the heat sink and transistor from Digikey. Thank goodness they had stock:

I wish I'd seen your issue earlier, although sounds like you got it all figured out. Here's my story with the same part from when I had a Mondial QV back in the mid-1990s.

 

At the time, I worked at a small company that designed remote sensors, mainly for military applications. As such, prototype design and building meant we had a lady who was in charge of acquiring parts. Once I narrowed the problem to this component, I checked the price from Ferrari and honestly I think it was even more expensive than you just quoted. I then brought the part to our parts lady, we looked at it, figured out what it was, got the part number, and then called the parts supplier and asked for a sample saying it was a part we were considering using in production. So I got the part for free. Yay! :-) I just had to mount it back on the original heat sink.

 

The end.

Kudos to the help from Anthony. I have received much help over the past 20 years from the list and it is what makes it great.

If some of you will remember, I posted having a problem with the vent fan switch not working with my Mondial. Anthony Bauco contacted me off-list and we discussed this at length. He was very generous with his suggestions and help and with that, it’s running perfectly now.

 

Turns out it was a burnt-out power transistor, the main one that regulates power directly to the fan motor. Ferrari did a pitiful job of installing it, not giving it a chance to dissipate the heat generated by the transistor. He suggested a suitable heat sink that I modified so it could fit in the HVAC box in it’s original location. The original - flawed – part is close to $300. I’m in it for about a tenth of that. In Canadian dollars.

 

That’s what makes this list great. Much appreciated!
