Q: Ac noise ?
When I turn on the AC, I'm hearing the air conditioner doing a clicking sound, Ac clutch
is going click-click ol the time while driving?
I thought that click clutch sound was normal just once when you turn on the air but not ol the time, I could be wrong, maybe it's just normal or is a bad relay somewhere?
BTW is cooling great no complains, except that clicking sound.
Thanks..................

What year? The new Rangers are quite loud when the clutch engages and disengages. If the clicking is constant however, the system has a leak in it somewhere. It should engage for probably 10 seconds every now and then.

but why the clicking is there every 10 seconds?
Maybe I need to know how the AC works? I always thought the click noise is only heard when you turn the AC on the first time and that was it?
explain it to me please, and thank you again!

The compressor does exactly what it sounds like it does...it compresses the air in the A/C system. The compressor engages to build the system up to a certain pressure, then disengages until the system falls below a set amount, then re-engages and pumps it back up.
The clicking you hear is probably the compressor engaging, running for a few seconds (you can hear it if you really listen), then disengaging.

Usually this is caused by a low refrigerant charge. Once in awhile you might find a touchy low pressure switch, but the vast majority of the time is low R134a levels. Also if the outside temperature is still cool, this cycling of the compressor is normal.

BTW, how difficult is to use those rechargeable R134 kits for about $20, that you buy at the auto parts? Is it worth it or should I have done by a shop?
Q: if your AC refrigerant is low does it always mean that there's a leak or is it normal to evaporate after a few years?

It's not difficult. They will have instructions on how to hook it up appropriately. I haven't had to recharge mine, so I can't offer Ranger-specific instructions.
I would not think the systems would need to be regularly recharged...the system in my dad's GMC made it 10 years and was still cold when removed from the truck for an engine swap.

Yeah, the recharge kits aren't that hard to do.
Most A/C shops will check the charge with a good set of gauges for free. I would do that before any other changes are made.
The compressor is so loud kicking in on theses trucks because the clutch doesn't slip much. I can actually feel mine cut in driving down the road. It has to be hard on the tensioner and belt, but I guess it's good for the life of the compressor clutch.
A properly leak-free system is what you are going for and, no it will never evaporate. '70's GM products are good for holding their charges, still cold after all these years.

The refrigerant will leech thru the hoses and connections over time, especially if it isn't used for long periods. That is why it is recommended to run the system occasionally even in the winter time.
The refill kits from auto parts are not that difficult if you have a little background with the mechanics of the system. For the complete novice, you can get into trouble real quick. Let your local a/c shop do the re-charge. jd

The manufacturers have the system rigged so that the AC switches on when the windsheild defrost is on. This keeps the system active in the winter time to keep it from seizing up which cuts down on warranty claims. In any case, if the AC is switching on as often as cadriver says, it's low on juice.

Should the AC switch every 10 sec, or not?
How do I know if the AC is malfunctioning or switching on/off too often?

they're all right. get the system recharged with refrigerant. the fact that she's coming on every 10 sec is that there isn't enough gas on the low pessure side to compress back into liquid on the high pressure side. there's an accumulator on the system yhat stores liquid refrigerant until the system needs it for cooling. when you're low on coolant, that accumulator empties pretty quick, causing the compressor to kick in every 10 sec.
good luck
