1994 NISSAN HARDBODY A/C CONTROL PANEL INOP

[nissan670]

My 94 nissan hardbody 2.4L is having electrical problems since the day i installed an aftermarket cd player. Everything worked fine till one night i was driving home from work and the ac control panel went blank and wont come back on. i notice the only thing that works is the ac button activates the ac clutch but the panel, blower is inop.

PLEASE HELP

Check for blown fuses. Perhaps a stray wire shorted on the control panel as a result of the head unit installation.

ive checked the fuses all are ok, the radio works fine i actually reinstalled the stock radio but still no progress... The only thing i have not checked is the 2 blue colored relays.
