Position of diode in fuse box there is a black fuse marked on the top with a diode symbol. what is the correct positioning of that fuse?

It only goes in one way. You can't put it in backwards.,

In the I/C fuse block look for the "HVAC" and the "RDO/HVAC" fuses.

In the underhood fuse block look for the "A/C CLUTCH" fuse. The diode is clearly marked with the diode symbol.

Since the a/c compressor is ultimately controlled by the HVAC module and the PCM it would be wise to use a scan tool to see if both of those modules are communicating the correct info for an A/C request.

The battery terminals have a plus (+) and minus (-) symbol somewhere near the terminal studs. If you cannot find them, use a multimeter set to a proper DC Range. Place the probes on the studs. If the meter reads the voltage, then red probe is on the positive terminal, if the meter pulls backwards the black probe is on the positive terminal.

If using a digital multimeter, a (-) says that the red probe is on the negative terminal.

Mark your battery with a Sharpie somewhere to show the terminal studs.

Hi, I recommend you access the OBD panel to extract the trouble codes. Then send us the trouble codes for further advice. On 850 models the DLC is located in the engine compartment in front of the module box, behind the passenger side headlamp.

1. Open diagnostic socket cover and install selector cable into socket No. 2 for fuel injection codes or socket No. 6 (except Motronic systems) for ignition codes.
2. Turn the ignition switch to the ON position.
3. Enter control system 1 by pressing the button once. Hold the button for at least 1 second, but not more than 3.
4. Watch the diode light and count the number of flashes in the 3 flash series indicating a fault code. The flash series are separated by 3 second intervals. Note fault codes.

1f there are no fault codes in the diagnostic unit, the diode will flash 1-1-1 and the fuel system is operating correctly.

1. If diode light does not flash when button is pressed, or no code is flashed there is a problem with the soft-diagnostic system, proceed as follows:
   1. Check ground connections on the intake manifold, and the ground connection for the Lambda-sond at the right front mudguard.
   2. Check the fuses for the pump relay and the primary pump. On 240 models, fuses are located inside the engine compartment on the left side wheel well housing. On 760/780 models, fuses are located in the center console, just below the radio. On 740/940 models, fuses are located behind the ashtray. Access can be gained by removing the ashtray, and pressing upward on the tab marked electrical fuses press. On 850 models, the fuses are located on the left side of the engine compartment behind the strut mount plate. The fuses on 960 models are located on the far left side of the dashboard. The driver's door must be open to gain access to the fuses.
   3. Remove glove compartment, and check control unit ground connections.
   4. Turn the ignition switch to the OFF position. Remove control unit connector and connector protective sleeve.
   5. Check diagnostic socket by connecting a voltmeter between ground and No. 4 connection on the control unit connector. Reading should be 12 volts. If no voltage is present, check lead between control unit connector and fuse No. 1 in the fuse/relay box.
   6. Turn the ignition to the ON position, and install selector cable into the No. 2 socket on the diagnostic socket. Connect a voltmeter between ground and No. 12 connection on the control unit connector. Reading should be 12 volts. Press the button on diagnostic socket and note reading. Reading on the voltmeter should be 0 volts. If no voltage at the control unit is present, take reading at the diagnostic socket connector. If reading remains at 12 volts when button is pressed, check diagnostic socket.
   7. Connect a voltmeter between ground and the red/black lead on the diagnostic socket connector. Reading should be 12 volts.
   8. Connect a suitable ohmmeter between ground and the brown/black lead in the diagnostic socket connector. Reading should be 0 ohms.
   9. Turn the ignition to the OFF position. Connect ohmmeter between diagnostic socket selector cable and the pin under selector button. The ohmmeter should read infinity. Press the button and note the reading. The reading should be 0 ohms.
   10. Connect a suitable diode/multimeter tester, or equivalent, between the diagnostic socket diode light and the selector cable. Connect red test pin from the tester to pin under diode light and black test pin from tester to selector cable. A reading on the tester indicates correct diode light function. With no reading on tester, replace diagnostic socket.
   11. Check the system relay/primary relay by connecting a voltmeter between ground and the No. 9 connection on the control unit connector, then connect a jumper wire between ground and No. 21 connection on the control unit connector. The relay should activate and the reading should be 12 volts.
   
   
2. Press the diagnostic socket button. Note any additional fault codes.

The diagnostic system memory is full when it contains 3 fault codes. Until those codes are corrected and the memory erased, the system cannot give information on any other problems.

1. Press the diagnostic socket button for the third time to see if a third fault code is stored in the memory. If the diode light flashes the same code 1-1-1, there are no other codes in the memory.

Fig. Fig. 1: Push button once for mode 1
Push button twice for mode 2

Push button three times for mode 3

To clear the codes:

1. Turn the ignition switch to the ON position.
2. Read fault codes.
3. Press diagnostic socket button 1 time and hold for approximately 5 seconds. Release button. After 3 seconds the diode light should light up. While the light is still lit, press the button again and hold for approximately 5 seconds. After releasing the button, the diode light should go off.
4. To ensure that the memory is erased, press the button 1 time, for 1 second but not more than 3 seconds. The diode light should flash code 1-1-1.
5. Start and run engine. If engine will not start, correct the problem before proceeding and start over with Step 1.
6. Check to see if new fault codes have been stored in the memory by pressing the diagnostic socket button 1 time, for 1 second but not more than 3 seconds.
7. If fault code 1-1-1 flashes, it indicates that there are no additional fault codes stored in its memory.

check under the hood for black box,lift the cover off of black box,marked" main fuse and relay boxfuse positions should be marked on underside of the lid to main fuse panel box,that you have just removed.check for a blown headlamp fuse in that box. it's either a blown fuse in that box,or if only one headlights "out" it will be a blown bulb(headlight bulb) it's very unusual for both headlight bulbs to blow at once. so in saying that,look for a blown headlight fuse. thank you for choosing fixya.com.

+ POSITIVE IS THE RED BATTERY CABLE - BLACK CABLE IS THE BATTERY NEGATIVE GROUND CABLE.

The problem is the diode needs to be replaced. The dome light works in the "on" position, but does not work when any of the doors are opened. The diode itself is about half the size of a dime which you can buy from a kia dealer for less then $20. You don't have to disconnect the battery to do this.
1. Remove the kick panel which is right next to the foot rest on the drivers side and where the fuse box is located. You will have to pry open the door foot guard to get to the other screw for the kick panel.
2. right next to the fuses box there is a wiring harness wraped in black cloth like material or some type of harness cover, just peel it back or remove. You can feel the diode through the wrap.
3. the diode is in a sleeve like incasement or cover carefully pry open and slide the diode out.
4. replace diode with new one and your done.

has the battery been tested? sounds like low battery voltage, the diode would not be the cause most likely.

Red cap goes to positive and black cap/end goes to negative. What makes you think they did it wrong?

Look under the hood for a black plastic box that has fuses and relays in it. On the edge o the box will be a post sticking up that you can attach your positive cable to. It should have either a red cap on it or a symbol of a + sign with or with out a circle around it, probably in yellow. Then hook the negative (Black) one somewhere metal. It needs to be like the top on the strut or top od the engine where the loop is sticking up from it where it was originally installed, anyhting to complete a ground.
