The phone won’t quit ringing
ok, so the truck has always made this weird ringing sound. About every 10 seconds or so, an old timey telephone rings in the engine. Like it’s possessed by a switchboard operator from 1897. Doesn’t usually matter to me, but the wife makes fun of it, and the kid in the drive through asked about it today, so it’s time to be addressed.
Ive tried listening for it, but can’t identify it, nor can I figure out what would even be making that noise.
Heres a video: https://m.youtube.com/watch?v=xzu1Bg...ature=youtu.be
its about every 10 seconds, it doesn’t change based on rpms or vehicle speed.
Any ideas?

Alright, thank you everyone! Don’t know why I didn’t think about the ac before... But i could see the clutch engaging, and also made it go away by unplugging the electrical connector on the compressor.
Now - why is it making the noise, and doing it so often? I’ve never heard the compressor cycle like that in any other car I’ve ever been in, and the AC doesn’t work anyway... I’m guessing I’m out of refrigerant, so I have a leak somewhere to repair and then recharge?
Thoughts? Repair/investigation steps?

The only way the a/c comes on is by command. Your fan switch is either turned to the a/c position, a separate a/c switch is in the on position or you're in defrost mode. If your freon is low, the hi or low pressure switches won't close n the a/c clutch won't engage. To be fair, you could be low on freon, the system still has enough to turn on the a/c but not enough to properly "cool". If that's not it, I'm guessin' that the problem maybe within the mixer doors n that's why it never feels cold, but if the a/c is indeed working/cooling, a quick way to verify it is to look under the pickup n see if water is drippin' from the drain line.

Try putting the hvac **** in the off position. The compressor should not run at all unless there is a problem with hvac switch. Compressor should only run on ac and defrost. It sounds like it's not staying on long enough to get water from the drain just feel the line coming out of the compressor and see if it's cold.

The cheap way to fix it is to leave it unplugged. If you want A/C you'll have to figure out what's wrong. It could be low on freon, or a sensor might have failed, the orifice also could be plugged. The clutches do wear out. I don't know if you can buy the clutch separately, or have to buy a complete compressor. You can buy the bearing for the clutch.

So, it was in the vent only (not AC) setting, but it does stop cycling when I turn it to off.
Temp does change all the way to heat when I change it to heat, and back again to “cool” (same as outside) when I turn it to cool.
Did not notice any water dripping/condensation, and pipes don’t feel cold...
i dont want to take it in, but also don’t want to catch an earful when it’s 110 degrees next month.
