from the problem description, it sounds like a wiring/setup problem with the speakers. check to make sure you are only using the main 'a' front r & l speaker connectors. if you select speaker set a + b on the front, you will not have the rear channels. please see the speaker connection guidelines in the manual on page 13-15. make sure the audessey mike and/or headphones are not plugged in when trying to use the speaker set up function.
Are you sure you wired up the head unit correctly? It is fairly uncommon for a audio output amplifier to blow out leaving 3 working speakers and 1 not working. So more than likely it is bad wiring or a blown speaker. Best bet would be get a digital multimeter and ohm out the speaker and see if it has continuity and is the same as the adjacent speaker. You could also try swapping the left/right channel wiring and see if the front right speaker stops working when connected to the left speaker output or vice versa.
check your speaker wiring, make sure both terminals are connected properly. or could just be left speaker is disconnected. and is set in stereo mode which will only play left and right front and Sub, if you have one. try chaning the surround mode to play in multi channel speaker which will send sound to all speakers. i trust your using a Digital audio cable from your source ( cable box, DVD player) if your using analog audio cable you will only get stereo sound, and nothing will ever come out of the rear speaker unless you change the surround mode to multi- channel speaker. also in the setup menu you should be able to perform a speaker setup, make sure all your speakers are able to produce sound. follow speaker setup mode in menu, make sure you have checked the boxes or Yes to speaker you have in your system. then perform calibration and a test tone will come out of each speaker as you select them.
Well, very common with JVC's to loose channels, JVC's tend to burn out or, skip, or their channels die out. Easiest fix is to replace it with a Sony or Pioneer but if not an option then use the rear left channel to run both left front and left rear speakers. Wire the left front + and left rear + to the solid green rear + wire on the car harness adapter and the left negatives to the green w / black rear negative channel wire. This will be a temporary fix but you need to fix or replace the radio otherwise the speakers will draw aheavy load from the rear left channel of the radio and probably overheat or burn out on you with long time hearing or at high volumes.

if front left is working it is possible u have a dry solder on ur right channel line. try resoldering or if u want to know exactly where dry solder is, shake gently every right channel components and connections. if resoldering does not work it is possible u have a faulty ouput amp for ur right channel. if ur not sure about this i suggest u get it checked by a qualified tech.
Check the connection on the back of the receiver. Check the balance setting, make sure that it's in the middle. Try another mode like stereo, you should hear left and right front only. Also, if your receiver has an on screen menu, check the dB levels for the front and rear left speakers. Good luck!
If the speakers themselves work fine, then the problem lies within the amplifier output. The channels can go bad after hard use, they can be repaired but it may well exceed the cost of the amp if it is not just one channel. Also be sure that you are hooking up speakers that are rated for your amplifier by matching the OHM resistance of the amplifier to compatible speakers.
1) just trace the wire of working channel and plug out that and connect to opposite side of that channel
for example: if front left is not working, remove pin of front right and plug it into front left
after that listen the sound if front left is working then no need to open amplifier just check the wires of satellite speaker which is not working
how to check broken wire:
1) just observe your speaker nearly if you found any screw holes open it, if u can not find any screw holes remove front net which is fitted by press lock or any stepped groove, you can remove that and if you are removing front net you have to open speaker from casing then after you can find speaker's wire shouldered or bolted to it just check wire and go on after that u'll be sure that weather your speaker is failed or wire!!!
Try this - connect one pair of its speaker wires at a time and test it. Watch the polarity.
• Make sure all cube speaker arrays are connected to the proper terminals according to their position in your room. • Check to be sure all wires are connected to your surround receiver with the proper polarity (+ to + and – to – wires). Incorrect wiring can result in a total loss of module output. • Correct any wiring problems before you plug in your receiver and turn it on.
How do you know the receiver's Left channel isn't the fault? Sounds like a source issue.
take amp to a workbench, have a test speaker in hand, touch the speaker wires to each channel to see if all channels work. take each speaker to the amp and temporarily hook one at a time to see if any speaker is bad. if you eliminate the hardware, you know it's the wires in between.
