Customer:

where would i find headlamp connector 1?

tims auto repair :

i would think the problem is the multi-function switch

tims auto repair :

these will burn out sometimes

Customer:

do you mean on the steering column?

tims auto repair :

yes

Customer:

i replaced that with a brand new one, with the same result. I tried that first

tims auto repair :

the dimmer?

tims auto repair :

you replaced it?

Customer:

no not the dimmer, the headlamp switch/turn signal switch

tims auto repair :

ok

tims auto repair :

the in-dash dimmer?

Customer:

the in dash dimmer has not been replaced

tims auto repair :

what you need to do,,is sit down with the diagram,,,,and just start testing

tims auto repair :

you are loosing power or ground between the switches and the relay

tims auto repair :

possible dimmer

Customer:

do the DRL use a reduced voltage as compared to low beams and high beams?

tims auto repair :

no

tims auto repair :

voltage is battery voltage

tims auto repair :

different circut

Customer:

i see

Customer:

i took a volt reading at the headlamp low beam side and read less that battery voltage, if that makes sense

tims auto repair :

well

tims auto repair :

we areloosing power to the lights we know

tims auto repair :

or they would work

Customer:

for sure. now that i know the dimmer is part of the equation i can factor that into chasing the power through the circuit

tims auto repair :

yes

tims auto repair :

it may be bad

Customer:

i hate electrical problems lol

tims auto repair :

but..use the diagram,,and test before you buy one

Customer:

i will, thnx
