Stopped getting air out of High side of HI/LO position on my ‘70 Vert A/C. Vacuum motor arm keeps popping off the air restrictor (?) door arm without a fastener. Can’t even find what type of fastener goes on the door arm in the shop manual. Lost one that looked like a 3/16 flat washer with a cross cutout in the middle. Not certain that was it either. Has anyone seen this type of fastener? The door arm is just a short rod, no grooves or threads.
Thanks.
There are spring clip washer type retainers that snap on the shaft end. It’s a fairly standard hardware/autoparts store item. It may also be available at WCCC.
Just what I needed. Thx for solving the fastener mystery. I had the wrong one.
Tried too hard forcing fastener on Hi/Lo door arm and broke the vacuum motor off the plenum mount. Delaying repair until pulling the dash pad. Made more work for myself.
