I took my RH temp blend motor out today, well the dist blend motor above it too.

The reason was to check the flappage for jams, however the flaps move freely which is a start.

The motor seemed to not turn but I applied some volts directly to it on the brown and black wires and it turns, but it is a little lumpy in turning.

Opened up and cleaned and it is a little better. I cannot see any missing teeth on the gears but it is not smooth running. If I run it without the small gear mounted on the pot then it turns smoothly and behaves. Cleaned the pot with switch cleaner, no different.

I see you can get the pot, but that seems ok with a meter on the wiper and either end so suspecting a gear issue as they do not look ok. Arrows are aligned on the main gear (with the indexing flat on it) and the pot gear.

Can you purchase replacement gears separately? or best just go for a new/used motor? I see some on that auction site for about a tenner each.

Thinking of swapping my dist motor into the position for now to prove a point to myself..........

Opinions? :)

Cheers
 
Sometimes all the motor needs is the carbon dust clearing from the armature. I had a blend that reported as short circuit. Stripped motor and washed carbon dust off, cleaned up armature, runs like a little clock. So blend has gone into my spares bin.
 
Mine needed sorting last year , didn't trust me to do it .
Paid a geezer 350 Inc set of 3 New motors .
It took him 3 hours ,nothing damaged or modified

Would have took me forever , wouldn't have gone back the same ,
Probably had a load of spare bits at the end .

No you definitely haven't done the job right if you HAVE got screws left over. And have replaced several missing ones the last dick who worked on it left out. :D:D
 
Now the O rings are done, I hope to swap the dist and RH motors tomorrow just to prove the motor does need replacing.
 
Old thread but just got all bits stripped out to access RH blend motor. Not much slack on the motor cable to attach connectors. If I remove LH tunnel trim and take Hevac out I presume will have better access to cable?

Cables from Hevac are clipped up rear of heater unit, without unclipping them what you have is what you got.
