a/c just died in 85 delta 88
drove the car for awhile this morning with a/c blasting
got in this afternoon and nothing,compressor will not kick on
put a new relay in,and replaced the 2 prong connector at the compressor
both of them were pretty melted up
still nothing
where do you check for 12 volts?
at the relay??

you can jumper the pressure switch with a short wire or paper clip to see if it turn on. if it does then you need more refrigerant. just don't run it like that. you can find the pressure switch on one of the lines, most of the time on the older cars, tord the front.

i tried the pressure switch trick,got nothing
my a/c has always been freezing cold,i cant see low freon charge being the culprit an hour after i drove it
i think it's electrical,im just trying to figure where else to look

I assume no check engine light...
Melted stuff is bad. Did you replace the connector at the relay? How did it look? If the terminals in the melted connectors are blackened, then contact will be inhibited.
Use a jumper wire to ground the brown wire from the relay to ground. If compressor engages, ECM is not telling the A/C it can work, or a bad connection between the two.
Ohm out your compressor clutch coil - they sometimes burn open.
Pretty simple circuit - here is the diagram...
