my 1996 sc300 has a issue with the climate control its going in and out one day it wants to work and the next it wont need help. my cars maintanence is up to date has new battery, timing belt, water pump change, my recent problem is the car is not starting up on the first key turning it clicks and or dies then on the second or third try it starts up, my next issue is my climate control is going in and out the back light is on and thats all that shows the defrosters and ac and heater light are off and cigarette lighter is not working, checked if i had anything in there and nothing, but at a random hour itlll turn back on when i drive my car again its weird need help i just want my car to be at 100% if anybody could help itll be much appreciated....
im thinking i might need to change spark plug wires, fuses, and ignition coil.

 

I don't think by changing those items would help the climate control and it's interment problem. I say check the unit itself and check the grounds.
