My truck has had this clicking sound when my heat or a/c is on since I got it. But now that im starting to use the a/c it is worse. And very annoying. when I turn the heat or a/c on some clicks really loud and my rpms jump for a brief second. Has anybody else had this or can tell me what to do????

I didnt know where to put this so I hope this is the right spot

 

That is normal. All the rangers do it.

 

Ford thought it was smart to run the a/c compressor like 90% of the time even if you have the heat up. The only time its off is off, face only, or feet only.

 

I thought it was off in OFF, FEET, or VENT only?

 

Face/vent. Same thing.

 

Damn I was really hoping to get rid of it

 

My truck does it also, it helps with moisture in the air by running the ac briefly,but is annoying as hell.

 

I always thought something was broke...welp cross that one off the list

 

it really shoudln't be that loud though. I can't even hear mine in the cab when i'm driving down the road. I can notice the idle change but that's about it. Make sure the a/c system is charged.

 

It keeps the seals lubed during the winter so they dont dry out

 

It should also cycle during defrost for the humidity right?

 

Every mode but off, face only and feet only.

 

mine started doing that today
