I'm having the intermittent problems reported by others with the air con working normally when the engine is cold, but then stopping cooling after about 10 minutes, particularly on a warm day. I've seen the advice about checking the air gap, but my 1997 CSE has a Sanden compressor rather than the Seiko type show on BillJ's site. There doesn't seem to be a gap to measure in front of the the pulley. Does anyone know how to check and adjust the air gap on this model? Thanks.
