All in the same day my Oil pressure guage, Fuel guage and engine temp. guage stopped working. Could it be a fuse? Also, on same day my air conditioning unit was not on but you could hear a clicking sound directly behind the a/c controls. I cannot seem to operate the unit at all, but the fan works. What could be causing all this on same day? Also, I broke the support that holds open the hood. What should a new one cost?
