Well Thanks. The Switch Is In And Works Fine. Although My Fans Took A Pos 12 V Feed... ZORCH OUCH! (always test with a meter first!) I Was Afraid Id Run My Battery Down And My Main Audio Amp Was Always On So I Hooked Them Both Up To The +12 Feed That Stays On For 10 Mins. After You Shut The Key Off Or Until You Open The Door. I Installed A Switch For The Fans So I Can Keep The Fans From Running Needlessly In Cold Weather. The Amp Draw On That Feed Is Too High. So Ill Add A Relayed 12 V Feed Tomorrow. Kris

Many of us run high-speed fan overrides, and have for a few years. However, most members would benefit just the same knowing that both fans will come on high speed when the climate control is switched to AUTO. When the AC compressor comes on, both fans will go to high.

The 94 SE'* must be diffrent than most of the years. I Dont Have An Auto Setting. :cry: Hi Will. I Regret Not Going To WCBF 07 :D I Was Very Poor At The Time.

The AUTO setting is on all Bonnevilles with the Electronic Climate Control feature. But the fans will go on high if you have the A/C on in ANY car, not just ECC.

Right..

Knowing you had an SE, WillWrens post is inaccurate based on model. You can achieve the same if you leave the AC on. However then you use extra fuel for the compressor when it'* running.

My A/C causes a big hp drain too. slows me way down. :oops:

Having said all this, about over-riding the computer and forcing the high speed fans to come on, perhaps we should address the basic issue: Why the engine gets to 228 degrees. While this isn't really overheating, you may want to check your cooling system out. Does the theromostat work properly? Is the radiator flowing well? Usually if a car is more than 10 years old, the radiator is clogged around 50%. You can have it checked by a radiator shop pretty cheaply (a shop that you trust). If your radiator is clogged, my suggestion is to replace it (or have it re-cored if anybody does that any more) and not to run chemicals through it to clean it. Cheaper to run the chemicals but not as efficient and the "law of unintended consequences" kicks in and you may end up with lots of leaks in various places. If you get a new radiator, use only distilled water with your anti-freeze. Just suggestions--you may well have done all this already.

Keith..an engine idling in stop and go traffic or city traffic has no running fans until they kick on. This allows the engine to heat up to those temps easily.

I was quite happy being a 97 with pcm support and having the ability to have my fans programmed down to 180-190F. Now there is no fluctuation when I hit traffic.

Keith, All You Said About A New Radiator I Agree With. But Its A Matter Of Dollars. My Next Large Buy Will Be Alignment So I Dont Trash My Tires Etc. Bill, I Dont Fully Understand Your Post. I Dont Normally Drive With My Performance Chip In Place Though It Is Tuned To 180 F. Kris

What part don't you understand? I'll be more than happy to explain.
