Question about Cars & Trucks
Without testing hard to say ! Your gas gauge not working could be the gauge it self is bad or the sending unit in the fuel tank is bad or somthing wrong with the BCM body computer . Are you talking about blower motor not working ? The blower motor is controlled by the BCM . Do you know how to do electronic testing ? I don't know if this year does it or not but on some cadillacs if you push the off and warmer button on the climate control panel the vehicle will show codes or will go into diagnostic mode . Been a few years , i worked at a Caddy dealer back then .You can look at free wiring diagrams at http://bbbind.com/free_tsb.html After you enter vehicle info . year ,make , model and engine size under system click on HVAC then under subsystem HVAC controls will automatically show ! Click the search button , then click on each blue link one at a time . You will see the complexity of your vehicle . Body computer , climate control panel . All electronic ! Fuel sending unit is a input to the BCM ,from there it goes to the fuel data center .
