kicks in and out and does not cool very well? Any idea's

Your refrigerant is low.

I don't know alot about a/c, but that would cause the clutch to jumo
in and out?

The clutch is electric. The pressure switch in your system is cycling the
compressor off and on. A fully charged system will cycle longer, partially
charged will cycle for a shorter duration, and low or non charged system
will not cycle at all.

Refrigerant leak, maybe?
Have it checked by someone who knows what they're doing.

Now there is more to the story, I shouldn't say it doesnt cool when
the clutch kicks in it blows real cold air but now the wipers turn on
sporadically at times? I would assume some type of wiring issue?
Thanks for all your help

Different circuits, different issues.

Your getting a 2nd oinion, and it is the same as the first.
Your refridrant is low, or your low pressure switch is bad.
Actually, it cant be the switch. It wouldnt cycle with a bad switch.
Pop your hood and look at all the air conditioning hoses/lines, look
at where they go through the firewall, and where they go out to the
front of the truck. You will most likely see one that has oil on it
with some dirt. There is your leaker. Usually an O-Ring.
If your system is holding on to a charge, I would have it recharged
every season. R134a is cheap enough.
