Dawoo laganza 2009 heater fan swith not operational tried all fuses etc


Check for battery voltage at the switch, if none check for blown fuse or broken cable,if OK check voltage at fan, If none check for faulty cable or bad connection, if ok replace fan.

My 2008 saturn vue headlight on drivers side works on his beam but will not work on low beam. We checked the fuses they or ok


In the diagram for left low beam, the top wire color is voltage, black wire is ground. Check them both.
Have you tried swapping bulb from one side to the other to see if problem follows the bulb. If it does, then of course the bulb is the problem. Don't touch bulb with bare fingers. I can't rule out a wiring problem? At the proper fuse did you check for voltage, use a test lite.

1999 cadillac seville wiring diagram


Check wiring with a test light or volt meter. switch lights to low beam, connect volt meter N probe to a good ground then probe the light socket for the low beam power cable, should show battery voltage, now switch to high beam and test for battery voltage if ok remove the grounded meter probe and probe the cable in the socket that you have not tested this is the ground cable, battery voltage should show if ground cable is ok. If no voltage repair cable ,If voltage present check filament on bulb high beam perhaps the new bulb is faulty.

Won't crank won't start


There are two starter relays in this vehicle. One is in the fuse box, the other right on the starter. Pull the fuse box starter relay. Check for battery voltage on two of the cavities in the socket when you turn the key to the START position. If you see that, then check for ground on one of the other two cavities. If you see all those readings, try swapping the starter relay with another one of the same size and type.

Rear windshielf wiper not working


{: ) Check first the WPR fuse 20amp at the underhood fuseblock. If okay, check the operation of the REARWPR relay. You should hear or feel a click when you turn on the rear wiper switch. Or you can try swapping it with another similar relay that is known to be working. If not successful, then a deeper test should be performed like voltage and signal tests, testing for open or shorted components and the wirings.

Having trouble getting truck to start needs to put jumper cables to start battery still good


You need to take it for a Starter Draw test. This will show how much juice the starter needs to spin. Autozone and Oreillys will test for free.

If the starter tests good, have your battery voltage checked. On Ford products the batteries need to be fully charged which is about 13.2 - 13.4 Volts. Ford products have sensitive Antitheft sytems and when the Battery voltage drops to a predetermined level, the Theft system cuts the starter voltage down to 6- 7 Volts making it difficult to start.

Once you get these tests you will know whats going on. If the starter tests good you may have to connect a Voltmeter to the big cable down at the starter. Then have someone crank the engine and see how much Voltage is at the starter. If you have another battery at 13.2- 13.4 Volts just swap for a test and see what happens.

It won't turn over but the lights are working tho


Just because the lights work does not rule out the battery. Take the battery cables off, remove the battery and have it load tested. If ok, since the cables are off look at the ends of the cables and clean them if necessary, Reinstall the battery and try to start. If it cranks over your battery or connections to it was the problem. If it does not start you will need to check voltage to the starter. I would recommend using a volt meter but a 12v test light may also be used. Check the voltage to the large cable connected to the starter solenoid, make sure you have battery voltage (12volts). Next hook your meter to the smaller wire on your starter solenoid, this is the crank signal wire. With someone holding the key in start position check for voltage to the wire. Should have 12volts.If you have 12v on this wire then your starter is getting proper voltage and needs replacing. If no voltage is present the you will need th check that feed circuit. Could be a neutral safty switch or clutch switch(if you have one). Even the ignition switch could be bad. If no voltage is present on your solenoid signal wire get a wiring diagram and check voltage from switch to starter. Good luck!

Voltage drop test


A voltage drop test is done using a DVOM. Set the meter to the DC voltage scale. Depending on the side of the cicuit you are on, place the positive lead on the most positive end of the cable.(closest to the positive terminal) and the negative on the other side of your cable/connection.Then exercise it. ( IE: Turn the headlight switch when checking voltage drop across the ground). The meter should read as close to zero volts as possible. (acceptable to rise up to 0.03v on the ground side) The reading you get is the amount that the cable or connection you are checking is drawing from your 12v source. You should do this to check for concerns in a circuit, so do not clean the connections until you perform the test.I hope this is helpful, if you need more info., drop me a line.
