2005 GMC DRL problem

[gerry lecky]

my 05 sierra nevada has a drl and dash lite problem. my left side drl, radio power button lite, heater temp control lite on left side, right side transmission selector indicator lite all do not work. i have replaced all fuses and relays and traced all wires from drl to convenience panel and all are ok.,

any ideas? could it be the daylight sensor on the dash panel is only turning on the one side? does it control a module somewhere? Dealer inquiry gave me no answers??

help appreciated

My factory head unit does the same thing
half is lit up and no more
I haven't pulled it but the original owner told me it went out when they had an iPod integration installed

Very odd to me

I'd like to know also
my 2500hd had that issue with the cluster, replaced it and poof it was fixed
