Looking for old Tech How-To Articles from this Site

Recommended Posts

Good Day! I hope you're enjoying a pleasant one. It's been a while since I've visited this site. I have a '90 Lumina Coupe, and a 91 Sunbird Convertible, both with the 3.1 V6 (both now on the project pending list). I thought I saw a couple of articles here, from long ago, that might come in handy now. One was a wiring diagram to install an under dash switch to bypass the computer for turning on the cooling fan manually. Another article gave instructions for resetting the computer after disconnecting the battery. I looked in the FAQ section but had no luck. Are they here somewhere, moved, hidden? Does anybody know what I'm talking about and can maybe point me in the right direction?

 

Respectfully,

 

John V. Brennan

I can post a simple drawing to enable the fan tonight without throwing codes. As for resetting the PCM, your cars are early passkey if any at all. Leaving the PCM unplugged for 10 minutes will clear any codes.
