Ferrari Mailing List: Re: Ferrari Mondial HVAC issue fixed

[Peter Rychel (dino308gt4]

Britt, keep this in mind with your TR. It uses the same transistor in a similar fashion and is subject to failure as well. If it does fail with the tell-tale signs (no fan at all, or full blast), it’s this part.

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!
