My car has recently started to go way down on idle when fan kicks on when I am sitting at a stop light or something like that. Car isn't over heating or anything like that. Anyone have any advice what could be causing it?

 

Sounds like an electrical problem. Do you have a large sound system installed, how old is your battery?

 

No I don't. And battery is only like 2 yrs old. Its only the fan that does it and that's what I am confused

 

have the alternator tested

 

So are there any problems when you cut on the a/c, heat or roll the windows up?

 

Nope. Just idles down real low when fan kicks on then goes right back to normal. Just sounds like its goin to die

 

Its definitely an electrical problem, check fuses, wires, alternator, battery.

 

Ok thanks guys for all the info. I'll check into all you have recommended
