It may be the fuel pump relay. https://www.google.com/search?q=mobile+auto+electrician+near+me ..

The coupler is not the issue. You need to pull the whole unit and check the vanes.

Have some one tap it for you while you're under the hood to track it down and then disconnect at least one of the wires. You can also try looking at your fuse box or where ever your relays are and look for the horn or horn picture. Either of those should do the trick so whatever's easier.

the last one I did was on the passenger side on top of the intake. it was covered with a flat plate that was held in place with 2 bolts I think. remove the plate and the PCV is under the cover. pull out valve there is a spring between the cover and the valve, make sure it is put back in place when re-assembling. it does not use a hose to control crankcase pressures.

You can also purchase a shorter belt designed for ?the same vehicle without A/C option.should be a belt diagram for both options under ?the hood. Hope that helps

It could be that your brake fluid reservoir is empty. You might also have a crack in the line.

It's not a module, it's a relay. And it doesn't run the windows or the radio. And both of them are on separate circuits. The radio has a fuse and also has an amplifier which has a fuse also. The windows(all of them) work off a circuit breaker. I have never replaced a circuit breaker in a car. But they can go bad, like everything else. If all the windows quit at the same time, most likely it is a broken power or ground wire. They break in the drivers side door jam. There is a rubber boot between the door and body, this is where they break 99% of the time.

failed ignition lock cylinder needs replaced

Can be caused by a lean burn condition . If no engine codes show up may be normal if engine ran for long time in extreme cold, if it persists contact a reputable mechanic

ok hit the fuel tank wile some body keep the engine starting, hit it hard 2 or 3 times, if the car runs ok, the problem is your fuel pump. replace it. that happens when you run out of gas, because the fuel pump cools down when gasoline pass thru, if you run out of gas the pump get overheat and goes out, most of the time.

If the blower works and there is no hot air, you may have an issue with your heater core. Does it smell like coolant in the car?

Transmission trouble code could make bad shift. with scanner erase trouble code and try road test if it correct the problem. hope it helps

I really don't recommend such a thing.

It comes back up from where...?

I would replace the TPS sensor. If you have fuel pressure enough to start the car, then you probably have pressure always. Before turning the key to start, turn to ON. You should hear the fuel pump pressurizing the lines. Turn the car back off. Go under the hood and remove the cap to the Schrader Valve. Use a rag to catch any fuel when you depress the valve stem. If fuel comes out into your rag, you should have pressure. Try this a second time to be sure. I had this issue with my car shutting down. TPS sensor replacement fixed it. BUT...it could be vacuum lines, or another sensor fault. The TPS is a common issue. You may also want to clean your Mass Air Flow sensor with the proper solvent and technique.

Check that you don't have any air in your coolant system. There is a brass fitting near the area where you install the thermostat. Find the fitting, and (with the car running), have a shop towel ready to catch any fluid coming out of the air bleeder screw. Slowly keep turning the screw until you know the valve is open to where air could escape. You will have coolant coming out also, but this may be your problem. Also, you should get yourself a bottle of Water Wetter to add to your coolant directly to the radiator cap. This will increase the coolant's ability to cool much better.

You usually don't. Power steering pumps usually come with their own pulley, which is pressed on at the factory.

I had the same issue. You have to attach the vacuum line to your MAP sensor which is just left of the brake manifold in the rear/right of the engine bay.
