Is this an Electrical Issue?
Hello everyone,
Here is the issue with my 2006 Ford F250 XLT (5.4L) . When I turn on my heater or defrost system for about a 30 minute drive. My tachometer will drop to Zero. I have no problems when I turn on my AC unit. I changed my battery and checked the fuse under the dash. Everything looks good with the fuses. I also have power when my Tachometer needle drops to zero.
I just wanted to know if this is a ground issue or electrical issue. Does anyone know where I should start. Again it only happen when I turn on my heating unit.
Thanks,
