Heater blower stopped working

[DesertIslandBlue]

Hello all, a little guidance for those that may experience this fault.

As background, car was working perfectly. Took a short holiday in Germany for four days with car left parked on the drive at home. On return I jumped in the car last night and blower wouldn’t work! All climate controls lit and working but no fan…

Anyhow had a look this morning and tried the following:
Soft reset of Sync - still not working
Disconnect battery for one minute then reconnect- still not working
Check fuse in engine bay (not the easiest job, who thought this assembly was a good idea?) fuse okay.
Reassemble fuse box and hey presto a working fan!

The advice above was over the phone from my local dealer who couldn’t look at the car until next week.

If I were to experience this fault again, would remove and replace the two mass cable connectors on top of the fuse box first. Have since seen some advice on a Fiesta Mk8 OC forum which seems to corroborate this.

Hope someone will find the above useful…

Thanks for the information....As you say, hopefully it will help anyone else unfortunate enough to experience the problem.

I am experiencing the same problem, after the car has been idle for a while the fan does not work. I had also unplugged the fuse box to check the fuses, but they were all good. After I checked to see if there was an error code in the system the fan suddenly worked again.
That was a few months ago. Now again after a few days of standing still the same thing, but now disconnecting the two cables on the fuse box and checking for error codes doesn't work anymore...
Maybe after a few starts it will work again.
