Colorado transfer box clicking and check 4wd


New Member
Hi, this is driving me crazy! I have a2008 holden Colorado and the transfer control box in the drivers footwell will not stop clicking! It's like the relay is going nuts. When it clicks I cannot change into 4wd or make it stop. Sometimes the check light comes on, I have used the three buttons to reset. I have. Just changed the control box to a new one but the click continues. Any ideas...?
