There is a relay, and mine is clicking ALOT on and around start up then stops after a bit, under the glove box, on the left side almost behind the radio area.

What is it for?????

I get this too.

I get a click from an ac relay or something related to ac, but it's more to the left I think. Turn your ac off and see if it still happens.

Is there an ac relay behind the radio/gove box area?

could be the heater / temp solenoids, they control the vacuum signal running to the heater control valve etc. By moving the temp dial left and right you can get these babies working.

just for clarification, items 2 & 3 in the diagram HVAC unit RHS was what i was refering too.

ok, now I don't hear the clicking and temps on AC output seem to be warmer.

I guess it is the temp solinoid. is it a relay that can be changed?

orange should be the airbag controller

The noise is most probably the control motors for the heating/vent flaps.
They usually start audibly clicking a while before they break....
It's normal for them to move at startup. Just turn the temp **** or vent levers to test !

So how do I fix this??? I definetly have a clicking coming from there. A nearly constant clickin over every single little bump or crack in the road or just whenever it feels like clicking... How do i make it go away???

toddk911

So the clicking is NOT a relay??

tommye

If it is the flap control motor(s), they will click repeatedly for a short while at startup and when changing temp. or vent settings. Stick your head under the dash and listen while fiddling with the buttons/levers !
To fix - replace the motor....

ALright will check the flap control motor. BTW does anyone know what these happen to cost???

There are some A/C relays behind the glovebox, but I think that's only in 83's, and its on the right side (near the door).
