I agree, sounds like it could be the pressure switch. If you don't mind messing with electrical stuff you can take the cover off and start the compressor to see if the contactors open when it hits 35 psi. If so I agree that the switch is probably toast unless for some reason the compressor was set up for low pressure operation. New switches are pretty cheap.
