I noticed today when I was sitting a drive thru that my engine clicks and the RPMs drop a little bit. Its a pretty loud click, I can hear it in the cab with the windows down. I've only noticed it at idle. The RPMs drop very slightly when it clicks, but thats the only thing that changes. Any ideas?

 

ac condenser?

 

Hum I had the heat/defrost on at the time, that could be it.

 

Remember that the compressor is on almost at any position of the climate control. I forgot what position keeps it off.

 

I noticed that mine does it sometimes too...

One of my friends said it could be the alternator.
And i didnt ever really notice it until i had the alternator rebuilt, but ive never had any problems.

 

Yeah I was thinking maybe the alternator as well, I'll watch the scangauge next time and see if the volts change when it does it.

 

Yep, it's the a/c cycling ... only positions it won't cycle are vent (through just the middle dash position) and heat(in the floor only position), or "off". Normal operation unless you get low on refrigerant causing it to click off and on in really short cycles.

 

Mine makes a loud clicking noise as well when I turn on my heat or A/C.. Yeah it's normal^

 

Ya, it is just the compressor. Mine is really loud and kicks on and off alot when used and sitting. Ya, like almost all of the positions it is on except for floor only and vent only.

 

If your "clicks" or a/c compessor cycles are more than about 5 seconds apart, your R-134 charge is low, or the pressure switch is faulty

 

mines like 3 seconds apart but the a/c is ice cold

 

Its probably 45 seconds apart if not more. I didn't time it.

 

it bugs the crap out of me. most of the time i leave it in the Off position.

 

I've never heard it until the other day, I never really have my truck running with the engine bay open though.

 

ya, it bothers the crap out of me

 

I miss my imports with a a/c switch.

 

Just turn the Vol button above the climate control and you want here it anymore. LOL LOL That's what I do!!!!

 

do you put tape over your check engine light too?

 

are you could do this works great

Off?

x2



I miss the 30+ mpg @ 80 mph w/ ac blasting too ... oh and the fact that 80 mph feels like nothing haha

 

Probably not even then.

 

Yep, it is normal.


It IS annoying. Sounds like something is broken. Ah well....another typical Ranger thing to add to the ever expanding list.


LOL.......I do in the work van. A business card slid into the crack hides the light pretty good. POS......plugs, wires, and injectors have all been replaced, and still there's a misfire error code in cylinder 6. Ah well.....what do I expect anyway, it's a 98 Ford Windstar and it's a company vehicle.

 

windstars are crap .... the camp i worked at over the summer had a 97 and the cel was on in that all summer ... even worse was the voyager they had.
