Car may start and run at other times all lights on dash come on fan motor comes on temp. light wont idle. Seems like a computor issue. Does it need reset ? where is it located? Car may run fine drive it 1 mile all lights may come on seems like a loose connection. Please help

 

sounds like something is loose..... for starters check battery cables. while doing that, disconnect negitive for 15, to 20 minutes. replace and make sure both cables are clean and making good connection. let the forum know how you make out with that, and welcome to the forum....
