The cigarette lighter has stopped working in your 1993 Mazda B2200 you have replaced the fuse but the lighter is still dead Could the socket need to be replaced If so how does one remove the dash?

There are two screws in the top of the dash facing around the instrument cluster above the clear shield,two more screws underneath near the steering column.Remove this next pull the fan switch knob and temperature switch off(slides off towards you).Remove the plastic knobs one for vent,heat,bi-level,etc, and fresh,recirculate off(straight pulling off towards yourself) they just stick onto the metal end where they attach.Now there will be one Phillips head screw exposed closest to the gauge cluster that once the gauge cluster facing is removed and,remove the two nuts that are at the fan,temp setting since the knobs are off.The only thing left is one screw behind a plastic cover plate on the right side at the fresh air knob.Use a small flat head screw driver to lift it up and remove that.Know the plastic with the vents,cubby hole, will come free.This will give you access to the 12 volt/cigarrette lighter.Disconnect the plug to it,not sure how this is held in place exactly.Just remove it and buy a new part,these are pretty common and the aftermarket versions should fit with a standard two prong plug in.I would suggest taking the original to the store to ensure a proper match.Hope this helps take like 10 minutes to remove parts above at most.You may have to use some needle nose pliers to pull the fan/temperature adjustment switch covers.
