Why don't my gas gauge and my heater work in my 1989 cadilac divel

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 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 .

1994 Nissan v6 4x4 king cab fuel gauge wont work but fuel pump works. What can I do to fix this?

see if you might have a bad ground on the gas tank where wires hook up to the top of gas tank. I don't know if you can reach up and move the wires around from side to side could have a bad connection. might have to let the gas tank down. have you tried to check your fuses first. if you find one for the fuel gauge pull it out look at real good make sure it is not burnt across inside by looking at the fuse what I usually do if you have another good fuse same amp is try a different fuse just to be sure.i use to work on cars a lot but had surgery on my back so from work history of 30 plus years of knowledge I hope I can help others. I hope this works let me know if this helps. you also might try to wiggle the wires around on the back of fuel gauge. you may also have a bad gas gauge but try what I said to try first. god bless

The door cover for the fuses is missing.need to know which fuse amp. goes in what spot...can't see my fuel reader. (don't know how much gas I have).

Not a fantastic answer but Try 10 amps in them all one by one until the fuel gauge works, Wont harm anything that way.

You really need the diagram!

Ever since we replace the fuel pump on our 97 Chevy Blazer the fuel gauge reads a quarter tank no matter how much gas is in there. Is their a fuse that may need replacing?? All the other gauges are fine, I...

float assembly, called fuel sending unit.May be able to access under the carpet in the rear or you may have to drop the tank. If you replaced your fuel pump you probably saw it.

If its just your fuel gauge that has stopped its not a fuse... the fuel sending unit's fuse is not dedicated to just the sending unit.. Sounds like sending unit failure.

If all the other gauges are working, then it is definately the sending unit. Mine is out at the moment and has been all summer. Pain in the **** to fix so haven't yet. Have to know however cause the fuel pump went out. Gonna kill 2 birds with 1 stone. We have just been using the digital reader for fuel used to know how much gas is in it. The gas gauge will bounce between half and full but never go below half.
