2005 gmc savana reset check light after oil change

The Check Engine light has nothing to do with the oil needing to be changed. Please read on.

When the service engine soon light a yellow light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

The fan in my 2002 GMC Savana cargo van doesn't work. I lost low, then medium speed, and finally the high speed.I checked the fuses and relays.I changed the blower resister, still no fan. The heat

Hi Jim, If the vehicle is fitted with climate control it will have electronic management. However it can be wired by someone knowing electrical circuitry to by pass the control. It will save you some cash but will need manual control. Make sure whoever does the job knows what he or she is doing. Have a happy new year. Regards John

1999 1500 gmc savana wont start, it ran great, parked and now in the am it did not start...amp is good but oil gauge is low, we already add oil to it, it needed 2 qts...please help

May I ask how long since the last oil change? 2 quarts low is some serious oil loss. You are going to have to do some basic troubleshooting. Start by checking for blown fuses. Next, check to see if you are getting spark to the spark plugs. If you're getting spark, then check for fuel delivery. Do this by cranking the engine with the starter for a few seconds. Then pull one spark plug and see if it is wet with fuel. Let me know what you find and we will go from there. Good luck.
