Now I'm having trouble with the heater on our 99 Suburban. I checked the vacuum lines going to the solenoid valve on the dash. I checked the vacuum heater hose valve and it is working. I pulled the connector at solenoid and I’m not getting any power there. Are there any fuses inline? Could it be the controller at the dash? Any help would be appreciated.

Only thing I remember about my 96 when it died is I had to replace the control module or whatever it is called. The thing with the knobs.
