FWIW, a good procedure with the meter is to test a known good 12v. source, to make sure you've got a good ground & the meter is working/set right.

Just hooking to metal doesn't always work due to ungrounded parts or poor connections. (getting fooled is easy, getting dependable results takes some effort)

thanks , i tested my other focus' heat at the blower motor and when the switch was off both wires read about 11.5 then with the switch on 4 one wire read 11.5 the other read 0.
