Ok to start we have a 1990 Geo Storm GSI manual transmission.... the alternator went out and killed the battery so i charged the battery and started it to make sure it didnt just drain cuz it was a couple days not started.... well with the battery charged it started, when i pulled the battery the car died... so i said ok its the alternator... so i changed that.. well now the battery light wont go out..... then not 2 hours later a hole in the radiator come outta nowhere so i had to replace the radiator.... i pulled the temperature sensor outta the old radiator and put it in the new one and hooked the fan and everything up right well now the radiator fan wont come on..... all fuses are fine but its just overheating..... ive popped the hood and waited for fan but nothing..... if you bridge the radiator fan at the relay under the hood it comes on but the car wont turn it on and the temperature gauge inside still works.... any ideas???? im completly lost on this one.... please help
