Does 2004 GMC Sierra have a PVC Value?

A PCV valve located in the valve cover. It may be located on or near the intake manifold, as shown here. A PVC valve located on the valve cover, with the hose that leads to it removed. A hose leading to the PCV valve is often kept in place by a clamp

Often lights under a dash or indicators just blow out bulbs. If more than one thing isn't lighting and are centralized check fuses to see if its blown. Bulb or fuse. IMHO. MIGHT be a sensor on tranny too. Hope not.

Here's a video with detaile dinstrauctions and other people's fuse questions. New fuses?

Under the truck, on drivers side, between fuel tank and engine compartment, sort of under where the drives sit, against the frame.

The blower motor is on the passengers side under the dash.You might have to remove the a lower panel.This is the insulator panel.If the blower works at all just turn it on and follow the noise.Hope this helps.Good luck.

I doubt it....It could be a totally worn out engine.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

it could be on top of the tank

There is no longer an external fuel filter. The filter is built into the fuel pump module now.

if you don't see it along the left frame rail just ahead of the tank then it is in the tank
