If the outside mirrors don't heat up and there is power to them, most likely the problem is the heating element. Check continuity through the elements.

i have continuity to both mirrors. it dont make sense

To, but through as well?

i have continuity throught both mirrors and one is new

Ok. If you have continuity to and through both mirrors, and power to both mirrors, then the heating elements are defective. OR, you aren't getting enough current to them.

so how would i improve the current.

there as to be something to reduce the amps to the mirrors. i need a schematic for them.
