Interesting thread and good DIY fix that saves a ton of money. Just curious, did any of you folk also have a drained battery after letting the vehicle just sit before the blower issue ensued?

Yes. I have to charge my battery after about a week of it sitting.

Do you think it's related?

I did a lot of searching on the forum a few weeks back because I thought I had a battery drain issue (I actually did not as I figured out it was just temporary) and I read a number of times on different threads that if the battery voltage drains slowly over a number of days to a really low voltage, then some control modules get really "messed up" and go into a deep sleep state. Would explain why jumping it would reset it or wake it up.

I would invest in a CTEK/NOCO battery maintainer if the vehicle will be unused for more than three days.

Thanks, could be a good tip.

I assume it's this flat connector?

jefandjax, you are a star! Blower is working. Truly Newton was referring to you when he made his comment about standing on the shoulders of giants. You and Robert Hook.

Excellent fix and I didn't even get a spark.

Thank you!

Hi all,

Not want to ruin the party here, but that fix wont last. Your fan motor is on its way out and has stopped in a position where it is partly seized. Doing the short in the connector will put full power directly to the motor and free it from this position. I had this and did this trick 5-6 times before I replaced the fan motor. Newer been a problem since. All here: https://www.freel2.com/forum/topic33161.ht...c1506fe0cc

Just jumping onto this post as it's sort of related, I have an issue where the ventilation fan just keeps running, even with the key out. I can only stop it by removing the fuse.
Some have mentioned a fan module behind the glovebox so is there a chance this may have failed on or is there a relay somewhere else?
I should mention that the fan appears to run flat out and the fascia controls make no difference to the speed.

I seem to recall on this forum a number of times where heater blowers went to sleep after prolonged switch off. It happened to my son a few years back, we had been away on holiday for a few weeks and when he started up the heater and blower were not functioning. He drove off in disgust and a little while later called to say that it had started coming back to life and eventually working OK again. It was never a problem after that. 3 x FL1 2 manual + 1 auto
