Heater problems
« on: June 18, 2020, 12:50:41 am »
Down here in the southern parts of Oz it's getting cold. So, a little dismayed to find the heater not working.

All other controls seem to be OK, when asked the car happily blows COLD air, and the air direction controls work, but as I say no heat. This is after letting it get to op temp, as the dash clearly shows me. To answer the other often-asked question, plenty of coolant. And, a quick probe under the dash seems to indicate the heater matrix is getting warm.

I've had a quick search and if I understand correctly, the Abarth/Fiat 500 of 2011 vintage controls the heat by a mixer flap, rather than by a heater tap (i.e. water is always flowing through the heater matrix, it's just a matter of how much air goes through the matrix).

Also, it seems this mixer mechanism can break (motor or flap) AND a HUGE amount of the interior needs to come out to replace it...

So:

- am I correct about the heater workings (mixer flap, etc.)?
- and are heater repairs as bad as it seems? (I found this: https://www.fiatforum.com/500/448013-heater-flap.html

Suggestions/other web links welcomed! Thanks in advance.

    ...and I also meant to post a pic from a "linked link" to show the ...ah... "fun" that was had in getting to the heater:
