Your going to need a multimeter to test the circuits.I would start by going over all the work that was done to replace the head gaskets.Sounds like maybe a ground wire was left off.

I would be looking for loose wires/grounds etc under the hood where you did the head gaskets.If everything worked before the head gaskets were replaced then something was left undone or pinched.Did you check all the fuses for power to both sides of them?

its the a/c panel.if u remove the lower dash panels youll see a black and a white connecter to the panel u can unplug them.if u cant remove them youll have to remove the dic. to see if the speedo lites.the ant. has a broken ant. mast assy.try to pull it up and down. check to see if its unpluged.the trunk is a broken drive gear or a faulty pulldown switch.the inside lights work off a photo cell in the center of the dash under the defroster grid.it pops in and out. ty for using 2carpros
