Control module where is the control module located in a 1997 chevy silverado one ton truck?

Jason,
The 2009 Chevy Silverado 1500 doesn't have a fuel pump relay. It has a fuel pump control module. If you are having an issue with your fuel pump and it is not the pump itself, just the cost of the fuel pump control module is about $177 from GM or about $95 after market.
Didn't know your motor size but have added a link that will give you a start searching.

Good luck.
Semper Fi,
Z

What problem are you having ? The engine control module controls the firing of the coils if you have the coil near plug ignition system ! Do you have 8 coils ? 4 wires going to each ? If so 1 is battery voltage, 1 is ground an 1 is a reference volt from the PCM an the other is a trigger signal from the PCM . Just if you don't know PCM is powertrain control module - engine computer . Do you have a misfire on one cylinder ?

The best way to get an answer for this go onto Youtube and they usually have fixrs for everything. Between last year and this year I have saved myself thousands of dollars repairing stuff myself through youtube.

The TCM is located on the fan shroud on the driver side of the truck. Its underneath a plastic cover but it's very easy to find. It is held on with two bolts at the top.

the transfer case control module is located behind the left side of dash behind the headlight switch, you will need to remove the speedo trim around speedometer, then pull put the headlight switch. the module is just snaped into place. also keep in mind, the module has to programmed with software for it to work correclty. in other words, the replacement module will have to be programmed after installing

1997 Chevrolet Astro is not equipped with a "Body Control Module". What, exactly are you having problems with?

The only thing left would be to check for power at the heater control. I've seen rodants chew through wires, is this possible

Hello Charles: My name is Roger and I Will help. The PCM is located behind the glove box on top of the heater case. The VCM is located under the hood just above the ABS unit.

The control module is located just behind the ignition coil. Sorta hard to get to but we got it and the van is running great.
