AC is not working, 2003 toyota corolla, ac compressor will not engage. Inside switch light stays on when pushed in. Checked low side pressure and it is 65 lbs.

Check the AC magnetic relay. 65 psi is way to high.

There is a free way to check it. Swap out the horn relay for the AC relay and see if the AC works. There could be other issues with the system besides the relay.
