Where is the cooling temperture switch located in a 1992 buick lesabre.I know the fans work because I ran jumper cables to the battery. Beyond that I need assistance. Any help will be greatly appreciated. Thank you very much.
The fans should come on at 109 c or about 219 temp f. You need a scan tool to see the temp and see if the signal goes to the relay to fire it up. You will need help here to verify this. If you jumped the fan and it works, it is a control issue.
