Land Rover Repair: A/C Blower Not turning on, power transistor, powerflow

Question
My  99 Disco II, (Which has the earlier Disco I Blower), does not get enough power to the blower to the turn it on, the A/C compressor is functioning correctly, and cools, but no Air, I check the two relays that feed the Blower, bt couldn't locate the Power transistor, How can I check to see what went bad, (The power supplied to one of the rELAYS, seems to be flaky)

Thanks

Answer
Hi Steve,

I read an interesting article (thread) awhile back about power feed to radio.   It was on the wwww.discoweb.org forum under the DISCOVERY technical section.  Perform a search on RADIO and you should find it.

It described the powerflow to the radio and which components are affected.  Should be good to use as reference in locating your fault.  

Best of luck,
