Have Honda Questions? Ask a Honda Repair Expert.
Hi this is dave from just answer, and I'm here to help with your Honda.
Did you install an aftermarket radio in the vehicle?
was the heat and a/c giving you any problems prior to the radio installation?
so right now you don't have at blower motor operation at all? Do the lights come on the panel for the heat and a/c unit
Did your crv come with stock navigation or just the standard radio
Did you install it yourself or was it done by a stereo store?
It sounds like something got unplugged on the heater box that is behind the dash or possibly on the heater control panel that is directly below. also just look at all the fuses under the dash to make sure they are not blown. Sometimes during radio installs if there is an accidental short of a wire its will blow a fuse. The Honda crv does not have many problems with the heat and a/c systems on those so the highest probability is that something became unplugged accidently or shorted.
Did you happen to look into the problem at all yet i never heard back from you?
