-air conditioner only works on high.
-exhaust manifold is cracked (know where i can find a cheap one?)
-doors rattle when music beats to loud.
-service engine light is on but no major visible problems.

first of all the loud ticking could be coming from the cracked manifold,secondly the aircon could be low on gas ,or the resistor in line for the fan speed could be burnt out ,they only work on full when this happens.The rattle in the doors could be loose window regulators or link rods .The engine light will only be diagnosed at a dealers or someone with a code cracker.
