Changed the oil myself for once. Didn't realize how easy it was on these trucks. My dad got in the habit of having our mechanic do it when he had a Ford because they were a PITA. I ended up having to drive a screwdriver though the old filter because none of my tools fit it :confused: but the new one went on no problem.

That's on my to-do list for this weekend. Need to do all 3 vehicles, but my son will be gone this weekend, so his will have to wait. I keep hearing how easy it is on our trucks, it's reassuring to hear it from someone who hasn't done it before.

Installed my oil catch can today. Simpler than I thought it would be, but it was a pain climbing up in the engine bay! Lol. 20170803_194542.jpg

Did you have a check engine light on for these codes?

Negative. But rear controls dont work right, recirc doesnt seem to work, and ac in general is temperamental.

I pulled those codes. Cleared them and pulled them again. Yanked the ac fuse, put back in and i think it ran the ac relearn. Cleared codes and the Codes are still there.

Looks like e-fan conversation.

Sounds about right. I've got a collection in that same spot but mine are for the eight horns I installed, mounted inside my front bumper...

Long story short I got tired of getting cut off and being ashamed after laying on my horn lol

Yeah I'm trying to work thru my problems I notice that mine seem to work ok when on manual fan mode and not when on auto mode. I pulled my passenger actuator out and opened the door still hot air either way? I'm thinking maybe the brains of it is going bad. I've done the fuse pull a ton of times never seems to help much. And I've replaced the passenger actuator
