Does anyone know just how to reset a business engine soon light ~ above a 2004 gmc envoy. I have actually done it once before. I think I removed the PCM fuses under the hood, however I cannot remember how to perform it and also cannot uncover it all over on here. I newly replace my water pump, thermostat, and radiator caps. I desire to view if the irradiate goes off. Any kind of ideas? I perform not have a code reader and also auto zone does no reset lock anymore.

Try disconnecting the battery because that 5 min. That should clear the computer system of any codes. If your light is tho on then the problem is most likely still there.Sent indigenous cost-free App

Or try fuses #10 & 28 in the underhood fuse box, these will certainly not cause feasible problems v the HVAC actuators.
