Last night tried to replace the bulb in my climate control to an amber bulb, removed the bezel and put in the new bulb but it didnt light up, so I did a check on the sockets and its getting power on the positive side but not the negative side. OK, I didnt disconnect any of the wires just removed the bezel so I have access to the bulb but now been working all morning and cant get it to work please HELP me out.
