GMC Repair: 92 buick park ave. air conditioner and oil gauge, buick park ave, oil pressure switch

Question
The air conditoner works part of the time and then other times won't work.

The oil gauge needle buries its's self and then will go back to normal and then later it buries again, (to the high side) but then will return to 40psi.

cruise control works sporadically.

Could these three things by related?

Answer
Hi,G

Sounds like they may be seperate issues,the ac problem may be low on charge,does the compressor come on?
The oil gauge could be a failed Oil Pressure switch.
The Cruise problem could be a few things,but the most common is the Cruise control servo that is failing.
