Q:

Drivers seat heater not working on 2004 Chevrolet Monte Carlo

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
The drivers heated seat button lights up but the seat does not get warm. The fuse is good, is there a relay that can be changed?
Thank you

The most common fault with the seat heaters is the heating elements, your 2004 Chevrolet Monte Carlo would be no exception. The upper and lower elements work in series so that if one fails they both stop working. The best way to test them is to check the resistance of each heating element separately. If one or both are out of spec the faulty element will need to be replace. This will involve removing the seat cover(s) as necessary to access the element.
