Instrument panel problems. 2003 GMC Envoy.
Hey all,I was given a 2003 GMC Envoy by my landlord,everything pretty much works,except the instrument panel,it works when it wants to,and the speedometer will not work at all,and the check engine and airbag lights are on. The engine and airbag lights stay on all the time but the instrument panel comes and goes when it pleases,and ALWAYS comes on when it's about to run out of gas. Really,really need this truck legal can anyone help me?? Please?? I do not have much $ so hoping for a somewhat easy fix
