Do the park lamps work ? license plate lights get power from same fuse ! Check ground wire ! use a volt meter an do voltage drop test ! Voltage Drop Testing The fuse for the license plate lights is in the under hood fuse box -engine compartment ! fuse #12 RT PRK LAMP 10Amp .

I believe you do not remove the lens - rather you open the trunk and find the back of the lamp (you'll have to remove the panel in front of it) and remove and change the bulbs from inside the trunk.

remove the plastic cover on the car boot. There is some screws that you need to remove front the plastic cover to get access to the lamps that illuminates the licence plate.
Replace the small lamps and voila !!!

First step check fuses. Next step use test light checking for power at license plate. A short will nearly always blow a fuse.

Yes i have had this before its because you have connected the wires wrong and used the feed for the lights ,cannot tell you the colours as i cannot remember and iam colour blind but this is whats wrong your 12v switchable feed what you think is the feed from the ignition is actually your illumination feed for the radio ,if in doubt run a new wire from the ignition switch direct to teh radiop this will cure it i promise ,Sorry i cannot tell, you what wire is what but when the reds and greens all look the same ?? you understand my plight but this is your problem i do know for sure as done two motors like this in the last few years .

The only way to get a code for the radio is from the dealer. Give them your license and registration to show the vehicle is yours. Then they will give you the code. This is for free, so dont let them charge you money.

Hi Joe here, The problem with your a/c is a sensor. Most likely the pressure sensor. You need to have the vehicle scanned to find out which sensor it is. 

Try turning the socket that holds the bulb to the left and pull it out to get to the bulb some times these get so hot that they start to melt so it might be hard to turn

If the car is a hatch back, there is a access panel in the middle of the interior panel, you should be able to access them from there, its a tight squeeze. If its just a four door you can access them from inside the trunk.
