No A/C
Hi Everyone,
I know very little about air conditioning systems, and for this, I apologize in advance. The A/C on my 2003 Accord LX up and quit yesterday. It had been pumping out frigidly cold air until my wife got in the car yesterday, and now the compressor won't switch on. The light on the dash comes on, but that's it. I don't know what happened and have no idea where to start. Any help would be greatly appreciated!
Thanks,
Mike

Check ac compressor fuse and if OK, check that 12V is available to the compressor when AC is turned to ON and keyswitch also On.
If 12V is available, the clutch coil could be failed open or the clutch gap could be excessive. If 12V not available, compressor relay could be faulty (best case scenario).
Excessive clutch plate gap prevents the clutch coil from pulling the clutch closed and engaging the compressor. Shim must be removed from beneath clutch plate to restore correct gap.
Failed open coil can be determined by measuring clutch coil resistance. Resistance will be high (open circuit) or very low (few ohms) if coil is good. Coil (or compressor) must be replaced.
This is not the place to start learning AC Repair. Repair may be fairly costly in either case (except failed fuse or relay0, as accessing the compressor may require system to be discharged.

Do you live where there are lots of rabbits, cottontails? Check for small wires leading to A/C, may have been cut.
Had Nissan Altima whose A/C quit. A small diameter wire had been cut leading to the A/C unit. Blame the rabbits
who climb into engine compartment to be safe from hawks / coyotes. (have observed them inside).
They have nothing else to do so sometimes they chew.
