The vacuum actuator for mode is on the LH side of center on a GMT400, right NITROUS? The temp and recirc actuators are electric but I'm pretty sure the mode actuator(s) are vacuum. Make sure the vacuum source from the engine is OK too.

I would start looking at the wiring to make sure something hasn't been pulled off. Some of the connectors are hard to see so look closely.
