Today somebody gave me an HVAC control unit out of an 04 Sierra W/T. Of course I took it apart and changed the bulbs, they were all burnt but 2. Replaced them with white LEDs. I think it looks good, you be the judge. It doesn't have the rear defog button like most higher end trucks.
My manual says to change oil and filter at 3000 miles. If you suspect the filter is going into bypass change it without changing the oil and this will eliminate one or the other. Are you using synthetic with a synthetic oil filter ?
03-04 are also known for the instrument panel to fail and remain on after key is removed. These will usually kill a battery within 3 days. But if your battery was 10 years old and lost a cell then it is unable to provide the regulated 11.0 volts to the sensors and the ECM will detect a fault at the first HO² heater test and it will fail and set a code, on our trucks it is usually P0031. It may set a few more codes if the ECM is in closed loop. Meaning if the engine was already hot at start-up. OP has the new battery fixed your issues?
Title says People Suck... I would like to add that 99.9% of people don't suck then you have the leeches of this earth that we have to deal with. It hurts my soul every time I see somebodies hard earned belonging get vandalized. Sacrilegious, these kids should have their a$$ kicked and tattooed with ''I'm a thief'' and see what their first girlfriend thinks of their a$$. Society in my opinion is too lenient on thieves and the justice systems can only punish to the laws extended definition. Too bad we law abiding citizens have to suffer from the lack of protection provided by the law.
Wife sits down with husband after he walks in with a six pack of beer.
'' I've been looking at our finances and we're scratching to make it every month ''
Husband: '' I Work as hard as I can and even put in extra hours ''
Wife : '' Maybe it would hepl if you quit buying beer every Friday ''
Husband: '' Only treat I get out of the whole week, but if you think it's necessary! ''
Two weeks maybe 3 goes by and one Friday evening she comes home with a little bag and drops on the kitchen counter with the keys as she goes on to her room to change and refresh. Husband cannot stop himself and gets up to have a peak at the little bag, inside he finds a receipt for over $100 and all he sees is a tube of lipstick,nail polish and make-up. Well he returns to his big chair in front of the game where normally he would have enjoyed a cold beer.
When she comes back she notice that her husband seems steaming mad about something.
Wife : '' What's wrong dear? ''
Husband: '' I thought we were suppose to cut back on expenses and here you come home with over $100 worth of beauty aid''
Wife : '' Well that's to make myself pretty and sexy for you ''
Husband: '' What do you think the beer was for? ''
The screaming could be heard for miles until the ambulance came. He now sleeps alone with a cold beer.
