The door locks on my 2002 Hyundai Sonata don't respond to the door switch or the remote when trying to lock the doors. The remote will unlock all doors but will not lock the doors. The door switch will not lock or unlock the doors. Someone suggested replacing the door lock relay. I cannot gain access to the door lock relay as it appears to be behind the fusebox under the lower left dash panel. Does anyone know how to remove the dash panel to access the relays or is there an easier way to replace the door lock relay?

Disassemble the paneling on left side ,under the steering wheel. Remove all screws and pull out the panel until you can you can reach behind it to remove the two Black Relays, on the side closest to Steering wheel. Remove the Relay covers, Clean the contacts with a 1/8 fine strip of 600 wet/dry sand paper. Only place the paper between the contacts, and pull out while holding slight pressure on the relay Armature. Turn over the sandpaper and repeat once again. Very gently press the TOP resting contact pad closer to the armature, to lessen the gap between the contact points, so the armature doesn't have to travel as far to reach the closed contact position. Repeat the above with the other2nd Relay. Replace the covers, reinstall the relays And test the Door locks prior to buttoning up the paneling. Note, a pair of long needle nosed pliers will help in removing the relays. Just Grip the relay and rock in Forward and Backward as you apply upward pressure.

2001 hyundai sonata engine lights on being found out for engine code p0421
Catalyst System Efficiency Below Threshold (Bank 1)
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream O2 sensor reading should be fairly steady. Typically the P0420 code triggers the Check Engine Light if the readings of the two sensors are similar. This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.
A code P0420 may mean that one or more of the following has happened:
* Leaded fuel was used where unleaded was called for
* An oxygen sensor is not reading (functioning) properly
* The engine coolant temperature sensor is not working properly
* Damaged or leaking exhaust manifold
/ catalytic converter / exhaust pipe
* Retarded spark timing
* The oxygen sensors in front and behind the converter are reporting too similar of readings
To Do list
* Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
* Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
* Inspect the downstream heated oxygen sensor (HO2), replace if necessary
* Replace the catalytic converter

Yesterday, I was driving at about 40-45 mph, and all of a sudden the engine revs up to 3000-4000 rpms. I come to a stop light the engine is still at that same high level of rpms with my foot on the brake. I found that when I was going up a steep hill, I didn't need to put my foot on the accelerator because I was coasting just fine up a hill at 45 mph. We parked the car and it wouldn't turn back on. After not touching it for 30 minutes, we came back to the car and the check engine light was on and the problem was gone. I have a 2001 Hyundai Sonata Automatic V6.
THERE IS A TEMPERATURE SENSOR ON MOTOR WHICH CAUSES THIS PROBLEM... USUALLY IT SHOWS A NEGATIVE TEMP READING WHICH CONFUSES THE COMPUTER CAUSING IT TO REV UP....HAVE THE ENGINE DIAGNOSED ON A SCANNER....GOOD LUCK...

Power antenna broke and I need to replace it. How do I do this
Buy replacement antenna mast. Remove old one by unscrewing the retaining cap nut. Turn on the radio & let the antenna cable run all the way up while you pull on it to remove it.
Install the new antenna mast by turning the radio 'off' so the spool inside goes back to its beginning while you feed the cable of the new antenna down into the antenna mast hole.
Once the cable is all the way down, reinstall the retaining nut/cap and turn on the radio to allow the spool to run the antenna 'UP.'... cycle the radio ON and then OFF several times allowing the antenna to move all the way up and all the way down.
That's it!
