cut unit off for 3 or 4 minutes and ac blows cold again. New acutuator door, compressor ok, blower never stops running. Just blows hot air

Today I was driving in my truck and it stalled out as I was driving two separate times. I shut the truck completely off turned it back on and it was good. It's stalled out a third time and I had to give it gas for it to actually kick back on. Then the fourth time and now all it does is turn over I can hear the fuel pump turning on when I turn on my accessory.. help

It was fine then one day starting having trouble shifting into 2nd gear. It will shift but only at high rpms. Now the rest of the gears are shifting at high rpms. What are my options? There's no check engine light or anything.

I'm pretty sure the piston slap is my problem.

If I take off from a stop at a normal pace,that is when it'll blow warm air. If I take 3 to 4 miles to get my speed to 40mph it'll will continue to blue ice cold if I maintain my speeds between 40/50???

Codes were erased so I can't retrieve them and light won't come back on.just got a ticket from chp on way to work.smog tech tells me to it needs to be driven more.but it's been 3 months

Truck will start but then it'll die shortly after start and security light will stay on.

Ive talked with my local mechanic and were both at wits end.simple job removed serpentine,replaced a.c. and serpentine belts.did take off the air hose thing prior to removing belt. Did remove splash guard before replacing ac belt.did replace air hose,did not replace splash guard yet ( shouldn't matter) started truck,it started.i stoped it and got my tools together( they were on the radiator) went to start it again and it wont start now.

the pump doesn't seem to be pushing enough air to open the check valve. Could there be a dirty filter inside the pump?

It was running and then started acting like fuel pump or filter was going bad go dead set for a minute then crank back and may run a while then start missing and quit replaced filter pump good pressure but no spark to plugs so just turn over is it distributor or crank sensor

Air does not blow through dash vents

Crank position sensor code came up about a month ago. Replaced both cam and crank sensors. Ran great for a month then started having fuel pump related symptoms. Replaced fuel pump with AC Delco pump. Ran for 15 minutes then died and hasnt started since. Receiving knock sensor codes and crank position sensor codes. No spark. Any idea what could be going on or anything to check??

Wile driving yesterday out of no where my truck made a loude clunk and hard jerk. and it feels like my transmission or differential broke a tooth. I idle speed home and every 100 feet or so it made that sound and Jerked hard like it wanted to lock up. I do all my own work on my truck. Electrical & mechanical but my dumbshit book (Chilton manual) only gets me so far. I got her ass up, shoes off, and on jacks. I noticed wile taking off her shoes I could spin the tires wile she was in park. Drive shaft did not turn only wheels. Can you please tell me what you think the problem is? Need to get to my job I put on hold. Thank you very much for you time and help.
