Hi there.

We never know what is on a customer's mind when they post these requests. So please don't get upset if I ask you...

  • are you looking for us to provide you with a chart that will identify all the fuses and their location?
  • are you seeking technical guidance in diagnosing why the blower and the seat belt warning don't work? If yes, do you have access to and know how to use an automotive multimeter?
Customer: replied 5 months ago.
Well I looked at the chart in the manual and it didn't show where the correct fuse would be. Any guidance to the problem would be appreciated as my dad is sick so I'm doing this. I do not have access to a multimeter

I'm sorry to hear about your dad and hope he gets well soon :)

There are two fuses protecting the blower motor circuit; a 40 Amp fusible link in the fuse box near the battery and a 5 Amp fuse in the fuse box on the left lower side of the dash. Please see attached graphics.

If that doesn't do it, then you would need that multimeter for me to provide technical guidance on how to diagnose the issue.

Best Regards.

Neither are blown

Sorry to hear that. Please know that I'll be here ready to guide you through a systematic diagnosis if you decide to get that multimeter.

Best Regards.
