See GM TSB 05-08-143-001, If you have Adjustable pedals, especially if they don't work with the memeory buttons, but function with thier own buttons. Its the Brake Pedal Position Sensor is shorted and mesing up the seat module which controls the heaters too. My 05 Suburban had the same issue

Does it work on any speeds? If it still works on high then the blower resistor is bad. On the passenger side under the glovebox is the blower motor and resistor.If possible try wiggling the pigtail plugs that attach to these two components.It is not uncommon to have problems with these pigtails.Also try tapping the bottom of the blower motor to see if it will start working again.If it does The connections are poor and need repaired. If the blower will not work at all check for power at the blower motor pigtail with a test light or dvm. Will be glad to assist further if more assistance is needed.

test to see if you have any power going through all the connectors for the seat heater, there may be a spot where there is a connector that has gone bad, or potentially it could be the whole element that is bad
