Weird, passenger seat heater lights are flashing

[toxicavenger70]

Has anyone had an issue like this? Another thing is the passenger side mirror intermittently works. I wonder if the two are related? Today I will probably disconnect the battery and see if that changes anything. I will also get the battery tested since it is about 4-5 years old.

I tested out the battery when I got home with the multimeter and it was putting out 12.3 volts not running. Which to me it is saying the battery is about 50% health. The battery in the car was replacement Ford H-9 flooded battery. The cheapest AGM battery I could find it town was a H-8 from Walmart for $165. And a $12 core charge. The car does have multiple locations for the battery hold down bracket, so you could fit a smaller battery in that location if need be. I just moved it up one notch to hold the H-8. It was not perfect. I did have open up the battery bracket bolt hole about a 1/16 inch to get the bolt to line up directly. Now the battery is putting out 13.2 volts not running.

It also seems like everything is working correctly.

Just an update, everything works but the passenger side seat heater. I will pull it apart soon to see if I can fix it. If anything I will buy an aftermarket seat heater element and replace the factory version. I am not spending $900 to replace the whole seat bottom/element unless I have to. Wish me luck.

Awesome! Thanks for the info. So one question, you disconnected your air bag with the battery still hooked up?

Thanks to the walkthru air540g I was able to fix the broken seat heater wire on my wife's car. The only thing not mentioned was a weird connector I had to figure out how to release. Here are a few pics.
