Default A/C problem

1999 RX

I turned my A/C on today and it blew cold for a bit then blew warm (no a/c) and repeated this on and off cycle all afternoon.

The outside temp was quite low 63f but the sun was very hot in the car hence the need for A/C. Could the cooler outside temp be the culprit?

Any ideas before I take it to Lexus

Does your '99 have auto climate? If so, that's what it sounds like.

Default fixed it

The pressure was too high...My fault, I put a shot of 134 in and pushed the pressure too high.
