Power Windows / Idle RPM

[vld]

I was sitting in traffic bored and farting around with the power windows when i noticed that if I continued to engage both switches at the same time while the windows were already up the engine dropped about 100 rpm. Does the same thing when I turn on the headlights. Normal?

well on the window switch with the windows beign either all the way up or down and it not realesed yeah the rpm's drop cause it putting a strain/load on teh charging system

same thing here, my lights dim along with the drop in rpms. i'm gonna find out how many volts my alternator is putting out just to make sure....

Same here, and I always wondered about how good the charging system is in this thing...

My Mustang and Ranger both do it.
