I bought my silverado a few months ago and have some questions if they could be answered that would be great! It'* a 2004 Silverado 2500HD with the 6.0L engine. I have read that there was a recall on the guage cluster and was wondering when this took place. My fuel guage and tac don't work and speedometer looks sticky its jumpy. My heat comes and goes it will work great for some days then others not at all then sometimes while driving it just quits. I've also heard a small knock/tick in the engine and I heard that a higher octane fuel would resolve this. Is that the case? If so would an octane booster suffice? If anyone could answer these questions that would be great!!

Well i just saw a tsb on the tick..dont remember if it covers your year and yes they are common to have guage cluster issues..as long as your truck has no tubo or supercharger you shouldnt need higher octane fuel as for the heat is its a elc control panel id look at it or your blower motor..

The recall is only good if your truck is under 100k miles. If not, you gotta pay. I know this because my gauge cluster had to replaced and I had to pay for it in my 2004 1500.

The tick should go away with a few tanks of high octane, high quality gas.

gauges- search google for silverado stepper motor theres a few write ups on how to change them yourself, fairly inexpensive.

heater- they have actuators in there that frequently go bad.

knock- some of them are noisey ive read they dont fit the pistons and that anymore just whatever tolerances they have.

Ok the heat seems to be doing ok for now. Last night my speedometer started staying at 30 like 0 and itgoes up from there. It only has 94k miles on it so the recall is still valid. Can anyone tell me where to go to get that fixed by any chance?

for recalls go to any dealer and they can run your vin to see if it has been done and if your truck is eligable

Its not a recall. Its a special policy on the cluster. the cutoff is 7 years or 80,000 miles and your vehicle has to fall within a certain VIN break. The dealer will more than likely say no but if you complain enough they will most likely cover the part if you pay labor. Call GM customer assistance if they wont help you at all.

When we took in our 04 the VIN fell within the right block but since it was over 100k they wouldn't do it for free. We ended up using the extended warranty we bought with the truck so it only cost use $100.
