The radio has no power. The fan on the climate controls are not working. No heat or A/C comes out. I replaced fuses and the relay in the fuse box inside vehicle. Battery was dead. Replaced with new one. Not the T95 battery.

Hi,

I'm looking through wiring schematics and the only thing I see in common between the two circuits may be the ground location. However, I need to know if your vehicle has a standard radio or one with a remote amp.

Also, let me know what fuses have been replaced, if anything on either of the two components works, if I am correct and the problem is the blower motor that isn't working, and if there are any other electrical components not working.

One other thought. When you checked the fuses and replaced them, did you confirm there is power to and from the fuse? If not, please confirm that for me.

Here is a link you may find helpful:

Let me know.

Okay. I replaced both the radio and the amp fuses. No luck. I replaced the relay for blower motor. No luck. I haven’t replaced the blower resistor yet.

Hi,

Was power present at both fuse locations? Also, before you replace the resister, check the orange wire at the resister to power when you request the blower on high, key on.

There are BCM fuses and an HVAC relay that may be an issue as well. See the pics below.

Let me know what you find.
