Never doubted you Dan, and thank you!

Jumping to real time without giving too much away it was a good day today!

The rear power window operated but was a bit sluggish. Since it had to be removed to access tailgate trim fasteners it's time to freshen up. The regulator it self required only a light cleaning and lube, but the motor was the crustiest mess I've encountered on the car. Fortunately it was clean on the inside.

I disassembled, blasted and painted the motor housing. After polishing the armature and brushes, lubed, reassembled and adjusted the motor and gear box assy. Reinstalled and the window now buzzes up and down like new. Lubed latches etc while there also.

To round out the good day my new neighbor and the local A/C wizard came by to bring the A/C to life. Thirty years ago the A/C got me home from CA with two cans of R-12, but hadn't ran since.

Duane brought along a new Delco dryer (he knows me well!) with a Made In China sticker on it I had set up with two 25' flex hoses to pipe exhaust outside (7 degrees) while running in the shop (70 degrees).

My cousin gave me a full R-12 canister a few years ago because it was obsolete for his farm equipment.

After evacuation held steady, time for a charge. Soo, I learned that the A/C control switch isn't sending power to the A/C clutch, worry about that later, jumper the clutch and away we go! The POA valve was a little stubborn but with a few light taps and a little patience with oil circulation, it was blowing 40 degrees a standstill idle.

A good day indeed!!

Thanks Bill! The rest of the car screams high desert 15% humidity, so why did that motor look like it went down on the Titanic??

Thanks Dan, lots of nice finishes were hidden under a half Century of grease and grime!

Bill, the early AC systems pull the full clutch load across the switch. Common for the switch to arc and foul up. Best to install a relay to take the load of the switch.. I did this on my 67 Chevelle and 68 Acadian and it fixed my issue. Learned this troubleshooting on my 68 Acadian... installed an NOS switch and only got about a dozen uses before it fouled out. Been fine since adding the relay.

NICE to have R12 !!

Awesome job on the wagon!!

I love that it’s not getting painted and you’re keeping the patina.
