The blower fan for the climate control runs when the key is turned on, with the engine off; however when the engine is running the blower fan will not come on. The headlight low beams come on with the key turned on and the engine not running, but when the engine is running the low beams will not turn on. High beams work?

SOURCE: no driving or high beam headlights

Hi,

To my knowledge a 2003 Toyota Camry uses a dual filament halogen bulb, either by Osram, Philips or Sylavania. If on the dashboard, the blue indicator lits when the switch is moved to bright or the passlight is engaged but no headlight, then it could jut be busted bulb (or part of it since you still have driving/low beam). In some cases, it could be the relay that supplies power direct to the bulb. At other times, it could be fuse(s) assigned to high beam. At certain instances, it could be also a loose, corroded or burned connector.

Corrective measure for your concern would be to check the 2 bulbs. This is performed by removing the rear covering (rubber or plastic cap) of the headlight assembly from the rear. The bulbs are held in place by a spring clip that needs to be unlatched from the base/holder. Carefully remove the bulb taking care not to touch the glass envelope. The filaments would be readily visible and cut/breaks would be apparent. If determined that one of the filaments (high beam) is open, replace the bulb(s).

If the bulbs prove to be OK, you need to work yourself backwards tracing the wiring harness. After the bulb, check the 3 prong connector for any corrosion or scorching/burnt marks; clean as maybe required. Next to check would be the relay that provides the +12VDC and then the fuse.

I doubt if the dashboard or steering wheel components involve with headlights may be at fault.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

I would Replace the blower Resister aka temperature heater fan resister.

SOURCE: headlights work on high beam but not on low beam is there a fuse

on these cars if 1 of the bulbs blow out then you will have to replace them both because they wont work. replace both headlight bulbs and they will be just fine

Sounds like the problem is more with the blower motor assembly itself. The blower motor have micro-proccers built itnto them which comunicate with the control heads and do the actual regulating of the fan motor. Dealers have computers with diagnostic software which allows them to monitor what is happening in the eletronic controls of the vehicle. Electronic diagnostics without the diagnostic software makes it very diffecult to pinpoint the actual item causing the problem.

SOUNDS LIKE INTEGRATED POWER MODULE(UNDERHOOD FUSEBLOCK)IS DEFECTIVE..ALSO CHECK FOR CORRODED TERMINALS IN CONNECTORS ON FUSEBLOCK..HAVE SEEN THIS BEFORE AND NEW FUSEBLOCK WAS NEEDED AND REPAIRED PROBLEM
