So i was cleaning the dash and the windshield wiper switch broke internaly. Umm is there away to replace that and if so does anyone have a one?

& my add coolant light goes off when i have full coolant.

 

if you're sure it's broken, replacement is just a matter of getting the replacement part and followiing the FSM.

for your coolant light, the sensor is probably frayed or otherwise broken and needs attention (replacement).
