My friend has a 91 CRX Si that has problems with the A/C. It works great when the compressor kicks in, but it won't kick in consistantly. You usually have to run it down the road a ways before the compressor comes on......then it will stay on unless you turn the A/C off. The schematic shows a 'delay box' but it doesn't tell me where it is, why it is there, can I adjust it/replace it or by-pass it. Does anyone know what the probem might be?

THANKS!!
