When it works it works fine. when it doesn't work no ac compressor and no fan. Blower in the vehicle works fine
Check low side pressure or try bypassing low pressure switch with a paper clip in the connector. If pressure is good but bypass works, you need a new pressure switch. If pressure is low, charge the system. If pressure and presxure switch are good, please get back to me and I'll do some research.

check the ac blower transistor under passenger side of dash behind the blower motor. on my 2003 compressor would not cut on , front blower only operated on high an blew hot air, rear blew on all speed but only hot air. $58.00 at dealer plus tax. 15 minute fix. there is a video on youtube that documents the process. just fixed today

Have you by any chance replaced the blower motor relay?
