i have a 2008 escalade with a heated seat problem, passenger side works good but driver side inop....the hvac led stays on no prob but u here the module click on and 10sec later u hear it click off......its got the heated TADS not elements it has the heated/cooling fans.....need helppppppp

Have you checked for voltage at the heater?

Yea 5volts

So if your getting voltage at the heater, and it'* not getting hot, then the heater is bad. Might be a broken wire inside the heater.

Just wanted to make you aware the vehicle has the Bumper to Bumper Warranty 4 years/50,000 miles. This may be something that is covered under the warranty.
