67coupedeville Posted May 22, 2005 Report Share Posted May 22, 2005 I remember a while back there was a procedure to turn the fan speed up. Some how from the factory it was set at something like 100, but you could turn the "High" setting up to around 160 somehow through the climate control to make it blow more air. Can someone tell me how to do this on my 91 Fleetwood? Spence Link to comment Share on other sites More sharing options...
Ranger Posted May 23, 2005 Report Share Posted May 23, 2005 I don't understand your question. Isn't there a fan speed button on the dash to over ride the speed ? Link to comment Share on other sites More sharing options...
67coupedeville Posted May 23, 2005 Author Report Share Posted May 23, 2005 I mean when you have the fan on High, it does not blow to its full potential. I thought there was something you could do to turn the high speed up even higher. There was something in the climate control that if you push the Off and Warmer buttons and you go into dianostics, there was something you could turn the fan high speed even higher. Any better?

Ranger Posted May 23, 2005 Report Share Posted May 23, 2005 Yeah, now I understand. You are talking about going into the PCM override section of the diagnostics. Beyond that I can't be of any help. I do not believe I have ever heard of what you are asking for. Perhaps someone else has. Link to comment Share on other sites More sharing options...
