E21 BMW ac problem

PPOT braintrust I present my problem.

1981 BMW 320i. The AC compressor cycles on then shuts off if you try to turn on the interior fan blower, then both do not work.

If I turn off the interior fan blower the compressor cycles back on, if I turn off the AC the fan will turn back on, both will not run together.

I suspect there is a relay issue, cannot find which relay.

Thanks in advance if anyone has personal knowledge and experience with this issue.
