Blower switch, wiring, or other?

[garbageguy]

Blower operation from switch used to be fine, but has progressed from an occasional problem to a more and more frequent one. Checked wiring and connections at switch are OK. Switch has 3 connections, 1 black, 2 yellow w/ stripe. If one of the yellows is disconnected from the switch, the switch light comes on when the switch is turned on, but the blower does not. If both yellows are connected neither the switch light or blower come on. It is a 1998 Wellcraft 240 SE with a fire suppression system. Any ideas appreciated. Thanks.

Ayuh,.... Check for Power, 'n ground, at the Blower,...

If both are present, replace the blower,...

Have both power and ground at the blower. Is there a way to bypass the switch to see if that's the problem? If both yellows (voltage?) and the black (ground?) wires were removed from the switch and connected together with test wires, should the blower run?
