The rear airconditioner does not turn on

When there has been heavy rains and driving through standing water in ditches etc or taking my mountaineer through car wash, my check/service engine light comes on and starts idling funny. At times when in park it will idle slow to almost dying then rev back up. Then when I get in and put in drive, it acts like its going to die and then revs up and goes. It has done this on and off. This last time though, I noticed the smell of gas at times. The light has now gone off and idling fine.

The check engine light is on. The truck is cutting of when slowing down to take a turn. Keeps cutting off when coming to a stop.

need price to r&r transfer case

Had timing chain replaced went to start truck and broke 4 rocker arms

Every time I try to reset it, it won't display the oil % life left. I press and hold reset and it just goes on to the next step of the system check.

Had my transmission looked at the fluid is clean a sensor replaced but it's still slipping the fluid is clean but it is shaking the whole truck I think it's something in the front end but people keep telling me the transmission is slipping love your phone and doesn't work right I would imagine the torque converters having trouble can you help me with this question

I don't have the $ to fix, priced around (600-1200) is there anything I can do (troubleshoot) short time?

i put a new radio in and shortly after lost dash lights tail lights and fog lights. Now i got in to take the truck up to the installer to see if he could figure out what happened and i suddenly have nothing when i turn the key it started to turnover and then just went dead. I am thinking this must be a relay but which relay. The battery as the 12V outlet has power

Also when going from reverse to drive car occasionally stalls out, any ideas?

Could it be from a vacuum leak or one of the sensors? Help

So I have replaced a few other solenoids on this SUV and had no problems however solenoid 3 has now burnt out 4 times, each time getting shorter from the last time. Just replacing the solenoid and spark plug is not enough. I have heard this is a problem with this vehicle but some suggestions would be great, thank you.
