I got some more work done today. There were a few holes in the liftgate and the driver's quarter panel. All holes on the quarter panel were rust holes, while the ones on the tailgate were from debadging, accompanied by a sick dent. I started yesterday by removing the obvious rust, and coating the remaining rust with Loctite Rust Converter. This morning, I plugged the holes with JB Weld mix stick, and by this afternoon, it was time for Bondo and sanding.
Then came primer. I used a high-grade Rustoleum filler/sandable primer.
That looks a lot better than rust holes. Now. it's been wicked hot outside, and the AC has not worked since I got the truck. I found out that the problem was 3-fold. The AC/Heat blend door actuator was not working and stuck on heat. The AC system had a decent seal leak, and it has no refrigerant.
I cut the core box open and manually set the blend door to AC, then loaded a can of Arctic Freeze large leak sealer into the low side port. Now comes time for the R134a.
The last time I loaded Freon into this thing, it all leaked out within a half hour. Now, it's been 7 hours, and it's still blowing ice cold. Good news on 90 degree days.
Now, next week's project is staring me in the face.
