Recently our truck has been having problems with the interior accessories. There is no power to the heater blower, radio, mirror adjustment, dome light, glove compartment light, etc.
The fuses and firewall connections are are good.
Does anyone have some suggestions of what may be wrong?
Thanks

fuse number 2 under hood controls mirror and radio number 1 fuse controls blower 13 controls heater so check all those first. actually check all your fuses either under hood or inside truck

that is different from your question then check the fusible links in both pictures. it should be battery voltage on both sides if not they are burnt out. auto parts have them.

have you checked fusible links yet? if you have then it may be a bad ignition switch not sending power to box.
