AC and idling problems
I posted about a "pulsing" problem while idling in my truck. As someone suggested I checked the alternator by disconnecting the battery with the engine running and accelerating a bit (with the car stopped, in "park" and e-brake engaged). Anyway, the truck ran fine and the alt needle went to the "charge" side of the gauge and stayed there. It actually did much better than with the battery connected.
When I went to reconnect the battery, I noticed a strange clicking noise while the engine was running. I connected the battery and saw that the AC compressor was cycling off and on when the click sound happened. The AC was turned on in the cab. Also, the compressor makes some strange noise when engaged. I took a short video of it.
I also took a video with the AC turned off. to show the difference. It runs much more smoothly of course. I'll take it out and see if the idling problems still occur. (please ignore the ice cream truck music)
BTW, I've been having issues with the AC not working too well. Lately it's gotten much worse and it barely blows cooler than the ambient temp.
Any input from those who know?
Thanks

I am taking the truck to a shop tomorrow to have the AC checked for leaks. I guess there is also the possibility that the switch which controls the clutch might be going bad..

I agree with all said above.....even though I'm not "with the times" I still tend to disconnect batteries on occasion. Anyways, sounds like low freon.....the "pulsing" idle is just the computer compensating for an increased lowed on the engine.....it's completely normal. Like already said, have your ac system checked.
