My 1990 Toyota Camry automatic 4 cy. Dash lite is off that shows the gears its

What is your question?

A man took part of the dash off , he didn't go behind the speedo meter and he said it was a special board or something not a bulb for it . Then when he put it back , my speedometer is wiggling and not right . Could a wire be squashed now for my speedometer to act up? And no hazard light ? But car can't get expected without the front gear shift changer lighting up. When I push the overdrive button , that shows up red . Please help me , I need my car inspection to get done . It's 2.0 engine. Dx or DL is the car .

How long has your 1990 Toyota Camry had this problem?
