Brutus you were right, it was a sticky vent valve.
The service guy explained to me that my vent valve isn't a spherical one like the normal ones you see, (thats why I was having trouble finding it by my tank). Mine is a square shaped valve, maybe because of the flex fuel?? who knows. Anyway...
Thanks man, ill start with the vent valve. I have seen that part your talking about that looks different, I never knew GM had a different part for the fix. Thanks again.
So im throwing a CEL and it is P0455, im sure you guys have read about this on here or experienced it yourselves. But I did some research on here and on google on this code. I have an 03 Yukon SLT with flex fuel
Its the large leak code. I replaced my purge valve solenoid on the intake...
I thought I read somewhere on here or another place to not bother switching out the little DRL bulbs under the headlights with LED's because they will not work.
Is that true?
If not, which LED part #bulbs can I switch them out with? I'd like white to match my HID's
Thanks
Autoride
and
Tire pressure sensors?
03 Yukon SLT 4X4
Reason I ask is all 4 of my tires were down to like 25 psi and I had no notification on my dash.
The constant buzzing when I get in the truck after a while, is that my air pressure from the autoride?
Sorry for the noob...
Ok noob questions.
Is the purpose of this mod just to have the 4 or 6 lights on at the same time while driving?
I just dont see the purpose of having the the 4 lights on at the same time, is it just for better light output?
So this may be a silly question, but are the headlight brackets on the back of the lights the same between regular Yukon and Yukon denali headlights?
Just making sure because of the projectors on the back of the denali HL's
I want to buy some denali headlights but both mounting brackets...
