RE: [DML] Re: Relay clicking with my AC on.



If it turns out to be cycling switch.( $7.95 ) You can change it out and if
it still cycles to much after you do the adjustment in the settings of the
mode switch and blower motor, you can change the setting in the cycling
switch about 1/4" clock and cut down on the cycling. Keep in mind that doing
this will begin to over burden then system, so don't keep on turning.

Yes! It is normal, but perhaps a little fast. As John Macias
mentioned, you may be a little low on freon.  The sound is the cooling
fan relay switching on and off with the AC compressor. Curious, do you
have the plywood board installed over the electrical compartment? If
not, the clicking is very prevelant; if so, it should be very muted.

In a stock wiring setup, there is no relay for the compressor itself
as Gus Schlachter said there was.  Perhaps his car is modified. The
compressor is directly powered through fuse #10, then the mode switch,
then the pressure switch(s), then tapped by dioes for switching on the
cooling fans, then into the compressor.

I find it unlikely that you have a circuit breaker popping every 5
seconds like David Teitelbaum and John Hervey mentioned, they dont
work that fast and are not nearly as loud as a relay.

As Joseph Kuchan said about the compressor clutch itself
engaging/disengaging, it is possible to hear that in the car and think
it is a relay if you have a leaky rear window.  My car was like that
until I re-sealed it.  Now I can only hear the cooling fan relay
activating in unison with the compressor (because I do not have the
plywood board over the electrical compartment).  Hope this answers
your question!
