Rav4 Clicking Relay noise

Hi, My wife’s 1995 5 Door Rav4 has developed a curious and very irritating “click” whenever the vehicle is moving there is a steady clicking like a relay closing every 3 seconds or so coming from the area below the steering wheel. Any suggestions as to the cause and remedy of this problem would be most welcome, it’s driving her crazy! Thanks in advance.

Drop the bottom of the dash, get the rig up on some jack stands (be safe) and run the rig. You'll need to SEE whats making the noise, then post something. Doing it as stated above is like fixing it over the phone.
