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


Rejoice!  The sound of relays clicking means that they're working.  :-)

One relay is for the compressor clutch, another for the cooling fans.  I 
have my fans wired to always run when A/C is selected, avoiding the 
constant electrical dips and surges.  I also have one relay for each fan.

If you really haven't done anything to your electrical system yet, then:

  1. Replace the fuses.  All of them.  Leave the cover off of the "fusebox 
  2. Clean the contacts of the relays.  Replace if necessary, or if 
paranoid and flush with cash.
  3. Clean and tighten the ground points.
  4. Upgrade the fan circuit breakers, although if you have the Fan Fail 
bypass this may have already been done.

If the clicking bothers you...upgrade the stereo with more wattage

I haven't done anything yet with regards to electrical systems in my 
car.  It has the Fan Relay bypass for the blue relay.  When I run the 
AC, I hear annoying relay clicks behind me, every five seconds or so. 
Is this normal?
