i have a 94 dodge cummisn and i dont think my grid heater is workin my truck the wait to start light stays on when its colder but it is still very difficult to start and if you keep turnin the key on and off and wait for wait to start light to go off it dont change anything someone help please

 

Do you have any codes? Mine gave me a code when the grid heater was not working. The connections are under the driver's side battery on a 99 anyway. You can make sure everything is connected before you look at the Morris code of your check engine light.

 

i have no lights on and do have a coolant warmer?
