My automatic daytime running lights turn off the moment I try to turn on my heater fan blower. The heater fan sometimes only works in position 5. The air conditioner won't turn on unless I manually turn on the headlights. The radio digital display sometimes goes blank or displays random LED segments. The rear defogger won't turn on.
The worst part is that it's intermittent, which causes me more grief because I can't bring it in for service unless the dealer can witness it.
Update from May 8, 2009: My automatic daytime running lights turn off the moment I try to turn on my heater fan blower. The heater fan sometimes only works in position 5. The air conditioner won't turn on unless I manually turn on the headlights or run the fan at position 5 with the air conditioning set at MAX. The radio digital display sometimes goes blank or displays random LED segments. The rear defogger won't turn on. Sometimes I can't turn off the air conditioner after I've gotten it to turn on. And worst off all, everything may work perfectly one day and not the next.
Update from May 9, 2009: I'll add a photo of the switch/harness.
Update from May 17, 2009: Added reminder....After you replace the switch/harness, make a point of turning off the fan before you switch off the ignition so the problem does not happen again.
