Does anyone know why an A/C pump would engage on and off for about 3 seconds? Would it be something electrical with the clutch solenoid or something as simple as low coolant? Its been real hot and the windows down just aren't cutting it.

 

It is normal for the AC compressor clutch to cycle on and off but yours is cycling too frequently. The most common cause for that is inadequate refrigerant in the system.

 

Dude! Whereabouts in Jersey are you from? I was born in Trenton but live in PA now. My one brother lives in Berlin, another brother nead Glassboro, and my mom and one sister near Voorhees.

We go offroading in Wharton State Forest over there quite a bit and have an outing planned for July if you're interested. Should be a lot of guys from the board here attending.

 

I'm from PA, have only been in Jersey for a year. Right now I live in Hopatcong, which is north. I've seen a lot about the Wharton meets, but I try to get out of New Jersey most weekends. So far they've all fallen on those weekends I'm gone but maybe sometime I'll make it down.

 

Cool. I'm glad to be out of New Jersey, truth be known. I've never been fond of the north. Despite being born in Trenton, I grew up in a rural farming community and not in the city.

It's not an accident that they don't charge bridge tolls to get INTO NJ, but they DO charge you to get OUT again!!!

 

is your a/c cold?

I just fixed this problem yesterday.
I was low on freeon (sp?) and my ac pump was cycling very fast because there wasnt enough freeon to go around.

I emptyed my freeon and fill it back up with some new stuff.
My air got down to 40 degree's. Ya it was COLD...

 

99.9% of the time, this is the low pressure switch turning it off. Your AC system probably needs to be recharged with R-134 or whatever the latest enviro-friendly coolant is. A 2001 shouldn't need this so have them look for a leak!
