My A/C started cycling warm and cold air. I put gauges on the system and they are reading normal in the A/c Auto position. But when I raised the RPM's to about 1500 I noticed that the Hi pressure got to about 300 psi.
But I noticed that the engine cooling fan did not come on with the A/C.
Once the engine temp called for the engine fan to come on the high pressure came down and the temp out of the vents cooled down.
I have no schematics, so where do I look for the relay/fuse/switch that turns on the fan when the A/C compressor comes on?
have the same problem?
