So just recently my blower motor started going out. And then shortly after that I start to hear horrible whining noise through radio and it gets worse. Then radio turns off, dash gauges stop working, whole dash goes dead but car stays running. Stays off for 30-45 seconds and comes back to life. Is the blower motor causing this in any way?? Since they both started at same time. Battery and alternator tested good. What else could be causing dash to die and annoying noise from radio?

 

i have a similar problem, just the whining noise through the radio and losing power to the dash lights etc
