Excuse my ignorance! I’m a carpenter not a mechanic.

I parked my 2005 Jimmy for the Winter, it was running great. I fired it up today and it keeps wanting to stall and I don’t remember this ticking in the fall before I parked it. Here’s a video.

 

Wait, how do I load a video???

 

It looks to me like you'll have to post the link to wherever you have it hosted at.

 

Was the gas tank full when you parked it? If it was not, water could have condensed inside the tank contaminating the fuel. Perhaps a water absorber could help?

 

Okay thanks, I put it on a link.

 

Are you talking about the clicking from your A/C compressor clutch cycling on and off? If so the compressor will try to protect itself from damage if there is not enough of a charge in the system by cycling off.

 

Yeah that’s what I was talking about. Is this bad?

This was not happening before it was parked for the winter.

 

Turn off your A/C and see if the truck still wants to stall. The clutch should not engage with A/C off. As far as the A/C system itself, it probably needs a recharge. I'd use a recharge with a dye to see if there is a small leak. Watch plenty of videos on recharging the system. If you overcharge, you can cause other problems.

EDIT: The compressor coming on should not be enough of a load on its own to stall your truck. Seems to be spinning freely, though it is possible there are bad bearings. It could be a symptom of another problem like fuel delivery, weak charging system, etc. But if the compressor is in bad enough shape, I suppose it could put enough of a load at idle to make it seem it wants to stall. Does it stall or almost stall? And does it go back to normal within a second or two?

P.S. The clutch "clicks" when the A/C comes on, so that's normal. You just don't notice it because it clicks once when you first turn A/C on.

 

I turned off the A/C and it stopped doing that.

 

I would just recharge the A/C system. Judging by the fact that the clutch is activating, you probably don't need much. One of the small 12oz cans should be more than enough. If you do it yourself don't try to go cheap. Get a can with dye in it and get a gauge. Both are sold at auto parts stores. It is really important you don't overfill. Watch good reputable videos before you attempt. You can really screw up the system and it will cost a ton more. Or just take to the shop. But I think the recharge should solve the issue.
