non workin radio

[PyRo]

i have an aftermarket radio which came with the car
when i bought it. it worked fine, for about lamost a
year and a half, until the other day when it stopped
working. It still turns on and has all normal
functions (can raise and lower the volume, switch
stations etc.) but absolutely no noise comes out of
the speakers. The weird thing is that when i go to
turn the radio on (or  it might even be when i turn
the car on) the red light for the outside temp on the
climate control blinks about 10-15 times then goes
away. Is this some sort of code. Im guessin it might
be a relay because when i turn the radio on, i hear a
click comin from somewherenear the steering wheel. any
ideas what it could be...as fun as it is, im tired of
listening to other peoples music while im sittin in
traffic.
thanks
