SOURCE: check engine light on
You cannot reset the check engine light any other way than using a scan tool. Some auto parts stores will scan the vehicle for free then at least you will know the area of the fault.

Cooling fan relay switch (in the fuse box uner the hood). Look for othger relays in there that are the same type number (they are all marked). If you find one that is the same as the cooling fan relay, then swap the two relays and check. (Turn on car and turn on A/C ... fan will start ... or not).
Fan motor could be bad (most likely).
If you remove it yourself, don't scrapr the radiator fins with the fan blades.
Hope this helps!

there is a large evaporative leak. keep away form ottozoo, they dont have the brain power to actually diagnose a light bulb., their job is to sell parts., if they sell you the wrong parts tough.Take it to a qualified repair shop that does a lot of GM work or the dealer.
