anyone else have the fan change speeds while engine is cold?i really notice this on defrost setting and highest fan speed.wondering if its the same deal as the lights dimming when starting out cold?

 

yeah I would say it has the same thing to do with the lights. when my grid heater is on everything dims my speackers even get quieter but I guess thats because I have a 800 watt amp<br>also.<br>DM01

 

I noticed the same thing. Matter of fact,,,, my Westach electric fuel pressure gauge dips down lower too. I reckon the grid heaters are robbing juice from the lift pump as well. [undecided] Also, I think that when running the defrost,,, the AC compressor is cycling on and off too.
