I hear a clicking noise under the dash every three seconds or so when I use the heat. I traced the noise to somewhere by the gas pedal. It only happens when I call for heat and have the fan on. Can anyone give me an idea of what it is?

I'm concerned because I don't believe there should be a relay that cycles on/off every three seconds. This would wear out the relay in short order. If it's normal - okay, I just want an understanding of which relay is clicking.

This car does not have automatic climate control. The heat works fine otherwise. I've only noticed this condition because this is the first time I've driven the car in the winter. It used to be a car my mother drove in Florida.

Are you 100% sure it is a relay? Even the manual climate system uses an electrically operated blend door to control air temp out the various vents based on the temp dial position. If the cheap plastic gears inside the blend door activator strip, you will get a click sound every few seconds as the motor tries to move the blend door to the comanded position. Try turning the temp control to warm or cool and see if the noise changes or stops.

I have a pretty good ear. It defenitely sounds like the fine subtle metallic click of a relay. The noise continues even when the temp control is at full hot, which is pretty much all the time here in Michigan. The clicking will only go away only when I turn the control to OFF.

i am having the same problem...and it is definetly an electrical relay cycling in the area of the fuse box to the left of the steering column....plus, i just recently did have the air mixing box and relay replaced(expensive) so i know that is not the problem.
just my 2 cents...

My rear window defroster relay clicks on and off by itself. The sound is coming from the fuse box area. Does the little indicator light for your rear defroster go on and off when you hear the noise?

A while ago I thought I had a similar problem with a relay click down by the accelerator, and it seemed to click on and off with my foot on the pedal... turned out to be the keys hanging from the ignition clinking together.

I hear the same click. Not every 3 seconds, but about every 15. At first I thought it was for the heated driver side mirror that doesn't work, but still tries, but even with the rear defrost off I still hear it with the heat on. I am missing my kick trim panel currently so I think it is louder for me because there is no buffer between me and the fusebox.

Would love to know what it is.

Oh and Hello everybody!

Heated mirrors are on same fuse as rear defroster. Mirror heat usually stops when one or both of the wires on backside of mirror glass falls off from old age. Electrically conductive epoxy will fix it.

Lol I don't think it was old age. I think it was the mailbox I clipped.
