Replace the EVAP purge solenoid. It is powered off the same fuse and it works as you are driving and not at idle . The MAF sensor is working all the time the engine is running.

    Vehicle blew the fuse again. Got it home, turned the vehicle off and replaced the fuse. Unplugged the MAF and turned the ignition on. Blew the fuse immediately. Looked at the harness for any signs of chaffing or chew marks and didn't see anything. Found the harness not in its clip at the battery and put it back where it goes and now it has quit blowing the fuse. Took the harness back out of the clip to try to isolate the short and it's still not blowing fuses. I'm stumped

    Have you unplugged the Evap purge solenoid. It is powered off the same fuse as the mass air flow sensor and it is near the egr valve so the wires are more accessible to heat.

SOURCE: 98 grand cherokee asd relay blowing fuse

The fuse it doing it's job, you have a short ( Wire that is connected to a ground, that draws too much power )

If you have an electrical schematic ( Repair manual ) find out which wires are connected to that fuse and check them for any chaffing, cuts, unnesassary twists, or corrosion.

If you have a ohm-meter, isolate the system ( by disconnecting the fuse, and other connections. Then check for any resistance on wires that should not be connected ( because you disconnected them ) by having one Lead on the wire's connector and the other meter-lead on your car's frame. A good wire will not have continuity if it is isolated.

Are you saying the fuse blows when you turn the key switch on ?
Could be a faulty injector, or a problem in the wiring harness, even the computer could have an internal short.

Even if my 2008 grand prix is completely warmed up, when I turn the fan on it only blows cold air.


Could be air in cooling system. Add antifreeze to cool radiator, run engine, cool, check level again, until completely full.

95 Grandprix will not start. Found the Fuel Injection fuse blown, Unplugged all injectors and fuse still blows. With ECM disconnected the fuse does not blow yet still has power


it will not blow when ECM is disconnected, cause there is no power to the injectors when you disconnect the ECM. When you turn ignition on check for fuel pressure at fuel rail. Release pressure at nipple on fuel rail. If no pressure exists puel pump is shot. If there is pressure your fuel filter might be plugged.
