The heat doesnt work in my 1997 lumnia

the actual switch to roll your window up, or is it the window motor? window switch is easy. all you have to do is remove door panel and disconnect the connector from the switch and pop it out of the panel and install the new one. window motor, you have to remove panel and there is a metal frame on inside the door that is sometimes riveted. if that's the case, you may need to rivet it after you pop the rivets. or some make a hole around the motor specifically there to replace the motor. shouldn't be a bad job. all you have to do is get in there and see what you got. not that hard of a job.

check your theristat

The vibrating sound is probably your heat shield on your exhaust,as you rev the engine the vibration is amplified and may be tripping your knock sensor, try removing the heat shield and see what happens.

Check fuel pressure at motor with a gauge
& see if it holds

I think the fuel pump has failed,maybe

If it is diesel, check battery. Week battery will not rev up the engine to generate enough heat for starting your engine.

Check oil of the transmission.. your transmission is slipping that's why you need to rev it alot to move !

check the crank shaft sensor its behind the starter they r cheap

The float in the carb is sticking..Buy a can of carb clean and spray it down as good as you can..In every hole and what you can get to...Alot of times this will work without having to take it off and clean it..After you spray it down really good let it sit for about 20 min.That will give it enough time to break down theat old gummy gas build up..After letting it sit Start it up..You may have to hold the gas pedal to the floor in order to start it because of the over satutration of the cleaner..After letting it run for awhile let it idle and go under the hood with it still idling and rev the motor up and closing the choke at the same time..You may have to rev it up a little high..When you rev it up and the motor is racing quick close the choke and the motor will start to die down and rev it a little with the choke on..What this does is by closing the choke when its reving up is it sucks all that crud build up out .You may have to do that a few times but it works great..Good Luck and Have a great day

sounds like the motor burned up due to a bad bearing in the motor itself will have to replace the motor.

check the fan motor by running 12 volts direct to it if it does not work then the motor is bad if it does check ur fuses and relays
