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.

A couple items worth noting. Found the key tag in between seat cushions, unfortunately it doesn't match car. Also an interior broadcast sheet turned up.

Not done with degreasing the engine, but getting started on firewall. First scrubbed with full strength Purple Power, then heavy compound followed by light compound and then wax. A lot of work!!

About this time I discovered NAPA Aluminum Brightener. What used to be 3-4 hours now became less than an hour! It cuts right through that desert hard pan grime. With progress moving along more quickly I worked from the firewall to the inner fenders and to the core support, removing components for thorough cleaning. Note the peeling paint on the RF fender inner jamb, more on that later.

Here are a couple of products I used to clean my engine compartment. Thought it may help.

Thank you! Always ready to try something new. The Purple Power wouldn't touch this grime, but the product on the left looks interesting. - Bill W

I found you need to be care ful with the scotch pads as they can scratch. I have even used very fine steel wool. The citrus stuff and simple green works when you let it soak. In the end it will look much better!

At this point I've not yet pulled the fenders, just concentration on engine and under hood sheet metal components. An example is before and after of the original voltage regulator. All the smog system was removed and given the same treatment along with alternator, pulleys and all brackets and attending hardware. The Brightener works great on wiring harness also!

I really don't want to know how many hours I've spent cleaning!!
