What kind of motor oil does a 93 dodge dynasty need?
Any kind of name brand 10w-30 oil should work just fine.
Where is the head light relay at on a 1990 dodge dynasty the lights wont come on and its not the fuses?
It is located behind the glovebox, above the heater/AC box. The heater core and AC must be removed to get at it. Good luck. It would be a good idea to get a manual, as many parts need to be removed to change the resistor. If you are good at wiring, you may want to change the location of the resistor.
