1. how do i turn my cab light on? i thought u just turned **** til it clicked but nothing? but when i open a door the cab light comes on so the bulb cant be bad, got any ideas??

2. when ever my AC compressor kicks on its really noisy, my ac still blows cold well in between cool and cold, it use to be colder but is it suppose to kick on and off like every 10 seconds, its really annoying

3. idk if this has to do with #2 or not but sometimes my truck runs badass, just smooth as hell and then other times it just feels so restrictive almost like 4x4 is engaged or im towing something, when i go to give it gas the engine gets real loud and sluggish, this one is my main concern, cause it literally feels like im loosing like 50 or more horserpower when this happens...

 

1. Sounds like headlight switch or wiring.
2. Sounds like compressor is going bad.
3. Sounds like tuneup issues if you haven't in a while.

 

As far as number one is concerned, you turn the **** for the headlights all the way to the left (I think?) until you feel it click. Then the dome light should turn on. If it doesn't or you don't feel a click, the switch may be bad.

 

on #3 someone at work said if the fan clutch was going bad, it could cause the engine to lag or feel slugish, can anyone back that up or is that not right?

 

Yeah that is a possibility. I'd take the whole fan off and see if it makes a difference. Obviously don't drive too long without the fan.
