I had that same Noise when I got my 2007 used expy, do yourself a favor and replace the spark plugs, the ones towards the rear have a tendency to get loose and you get that noise,it sounds like the phasers but it's not. i went with the champions that don't break when you remove them but that's...
Thank you all for your time and knowledge.
i finally figured it out.
The replacement bulb that I got had a different wattage than the one in place, and the computer was shutting down that bulb on the low-beam. got two bulbs with correct wattage and all good now.
Resistance is 0.6 ohms.
there have to be module that controls the lights cause according to the manual there is no relay for the low-beams. there is probably a cold solder in one of the resistors or contacts but i don't know were is located.
Positive to hot wire and
negative lead to chassis.
and cut the hot wire from the connector just in case
there was a short at the connector. same results.
I did follow the harness from the headlight and there is no apparent damage until it merges with the big harness, voltage on fuse 7&8 is 12v on all points I haven't check 23 but the other side high-beam is working fine. will try later and get all voltage reading from conector c2280a
replace bulb ,and checked fuses #7 and #8,check voltage and only getting 9volts to the low-beam and 11 V to high beam
ground and fuses are fine. Passenger side is all good. can someone provide the wiring diagram
for this car. or any suggestion will be appreciated.
the driver low-beam blinks...
