climate flap servo, more reliable ?

[mako]

Hi, all

servos for all three climate control flaps have stucked one by one.

went over many posts about failed valeo servos, I have replaced them. For the last one (recirculation flap), I just put the old servo which had already been detached from direction flap for the same failure. As you may know, a Brand-new costs a fortune.

Strangely enough, all removed Valeos ran just on a 3 or 4 volt DC. I guessed these faults were due to the loosely housed motors inside the unit and they only needed tight fixation.

a month ago, direction flap stopped again ! a brand-new valeo servo lasted only half a year. not like before, after being removed, it didn't run on 6 volt DC. finally caught red handed.


As has been pointed out, there was some metal dusts inside the motor, and it's electrical instability may have confused me.

not familiar with repairing dead motors, I put a new and almost the same specification motor into the unit. It costs only 50 Japanese yens.


Now my revived servo seems to work more powerful and faster than before, while motor sounds a little bigger.


I will watch how long it will last.

Hi Mako, for info, motors are rated at nominal 7.5Vdc.

The Valeo flap servo motors, when dismantled, appear to be very poorly made, rather like the kind of motor you would get in a kid's toy. Sadly, the XM and some other Cits were badly let down by quality issues in parts which failed when a few extra pounds here and there would have made them reliable. A £22K -£30K car shouldn't have such issues in my opinion.

certainly, the servos are marked with something like "7v" on it.
but my this failed motor didn't run at all on 7.5 v.

as far as I experienced before, they seem to run just on 3-4v while alive

I agree.
when I browsed for information about valeo servos, 4 rings people seemed to be tortured like us.

valeo, valeo,,, seems so popular around, why are they valeo ?

Hi Mako

Can you identify the actual motor you bought and the suppliers details.
That would help a lot.

Best regards

Hi, John

I just came across this motor in Osaka Nipponbasi electric town (like Akihabara in Tokyo). not sure If it could fit the Valeo, didn't ask them about who was the supplier.

I am to vist Osaka next Thursday.
I will ask the shop about details.

Hi, John

the maker is MABUCHI MOTOR CO., LTD.
http://www.mabuchi-motor.co.jp/en_US/index.html

the shop is
http://digit.kyohritsu.com/

I could not identify the product number in their websites, so I visited the shop and asked the shop assistant, but he knew nothing. the product itself has no number on it.

the tag says only "DC motor with worm gear" (more expensive than I remember)
