This weekend I was working on a Friends Suburban and before we put in the stereo the Heater and AC Seemed to work fine.
Now while installing the stereo we used a wiring harness. I hooked up the Illumination wires from the stereo to the illumination wires listed on the harness and it blew the Power Door Lock Fuse. After replacing the fuse the power locks work again.
But now when we turn on the Heater and AC the AC lights and Defrost Lights no longer Light up. The blower works fine but we are not getting any heat. Is this something that could have been caused from the stereo wiring?
Any ideas where to start looking. We have checked all of the fuses and wiring looks okay. Checked Coolany levels and all seems to be fine.
