i've been noticing lately that my driver's side mirror doesn't clear the fog / mist when i start the truck. the passenger side clears immediately.

if i activate the defroster the mirror slowly clears and i can see dots where the heat is being applied.

aren't the mirrors heated, no matter what, once the ignition is keyed?

i suspect i have an issue. my DRLs on the driver's side are burned out also. anyone believe these two issues could be related?
