started the thread with........
I have a 1995 C1500 and the AC in it works great cold and blows real strong. Mostly since the last owner had it completely redone (about 8 months ago) right before he sold it to me.
But the problem is that it has a very annoying constant clicking sound but what is really odd is during a turn the clicking will become softer same speed but not as loud.
If it is a sharp turn it will even stop completely.
Any help? Justin =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D After getting a few tips..... snipped-for-privacy@satx.rr.com.com (Justin=A0Spencer) reposted with:
Ok after thinking about it for a while I just now stupidly realized that it couldn't be the compressor turning on and off due to the sound being far too fast.
Since the speed of the sound increases when I turn the AC on a higher setting I thought that there was something in the fan. But after inspecting it and finding nothing I still had the sound.
So after following the great advice Marsh gave me I unplugged the pressure sensor and let it run for a while and the sound magically stopped.
I then plugged the sensor back in and the clicking was gone. I felt really good about myself for a while until the first hard turn and it came back but disappeared after straightening out.
And that is the problem now my original problem has completely reversed itself.
I am truly baffled. Justin "Justin Spencer" =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Justin, what's up with the latent diagnositic clues there bud?
Clicks faster as you turn up the AC? (really should'a ought'a put that in the OP)
anywhoo..... I'm still not sold on the fact that it's the AC that's causing the noise.
........ A FEW QUESTIONS ..if i may
Are you sure...??? Positve...???
100% sold on the fact..??? completely eliminated ANY POSSIBILITY???
that there's not something inside the blower motor housing that's rolling around as the truck pitch's from side to side on turns?
or....the blower motor isn't bolted up tight... maybe loose??
also.... have you tried running the system in the VENT or HEATER modes to see if the noise is still there?
also.....
If the truck is running in PARK, and you turn the steering wheel from side to side to the stop.....can you here the noise???
................... do this........
Make a 2-wire jumper wire long enough to reach from the AC Preasure Sensor harness connector to inside the truck.
(the cord off yer wifes vacume would work nicely)
Take yer "Uncle Henry" out yer pocket and skin the wires back on both ends.
Shove one set of the ends of the wires in the harness terminals good enough to be sure yer makeing a good connection.
Touch the other set of ends togeather just good enough to make a connection and chunk the wire in the passenger window and on the seat.
Drive the truck.....
take a couple of sharp turns....
when the noise starts...
unhook the wires and see if the clicking stops.
............. We don't want to go spending yer hard earned money on charging an AC system that isn't gonna fix yer complaint....we'de rather you buy us a beer with the money....after we narrow it down to a loose Wheel Well Sheild. (that you bumped with yer knee while unhooking the AC sensor)
........ (story time) (FWD vehical)
Got a call one morning from a customer that had picked up their vehical late the previous day. Seems on the way home SHE.....heard a mighty THUMP...and then bump,bump,bump as she rolled on down the hiway. The customer is a little irate bout the quality of the work SHE.....recieved....and demanded some satisfaction.
Towed the vehical in..... Test drove it....
bump,bump,bump....at wheel speed.
Put the vehical on the hoist....
D A M N.....!!!!!!!!!!
that shure is a big racoon wrapped around that axle.
