Hi Scotty, Love the channel! I have a classic car, a Rover Streetwise SE 2004 with the 1.4 K series engine.The air conditioning is not working and I suspect it's the pump, but I could be wrong. Could you advise me on a simple way for me to check the pump is working, without having to go through all the wiring and relays etc? The fuses seem ok, as does the relay. Thanks Scotty! Cheers...Howie from Scotland 🏴
Hi, Thanks for getting back to me. Actually, I haven't checked the manifold pressures, but I will now look at that issue. I visually checked the operation of the clutch, while a friend switched on the AC and it's not engaging. Does this mean the compressor pump is faulty? Thanks again, I really appreciate your advice! Cheers...Howie
Have you checked system pressures with a manifold gauge set? That will tell you right away whether the compressor is doing anything. You could also visually observe whether the compressor clutch is working, but that alone won't tell you whether the compressor is working internally.

It could mean there is insufficient refrigerant, the compressor clutch coil is bad, or you have an electrical or module problem preventing the clutch from engaging.
Thanks for your advice, I'll look further into what you suggested. Cheers...Howie
