I have acura legend 1991 and the ac blows cold and then warm then cold then warm on 1991 Acura Legend

The compressor is good, the ac has freon, all the switches work and just replaced the ac-radiator fan switch in the passanger side. I'm lost

Asked by for the 1991 Acura Legend
Do you have pressure guages to hook up to it? That may help in diagnosis. Is the compressor cycling or is it on constantly?

Might be your expansion valve that is clogged. You need to take it in for diagnosis.
