89 560SEC blower is running fine and suddenly dies. Checked fuses... all seem good, removed and checked connections on relays, some dirty, cleaned and reinstalled. Still will not blow.

Checked strip fuse, (next to fuse box and plugs into a socket like a relay, has 2 30A fuses), checked all fuses for power thru, still no power to fan motor. Used volt/ohm meter and have the lesser voltage at fan connection but no 12V. Did blue wire ground scenario, no fan. Everything now says switch to me. How do I remove and troubleshoot switch. Where does the voltage to fan speed switch come from? I hear everything energizing when climate control is turned on, no fan. Everything everyone has come up with so far has been in great detail and really makes the troubleshooting easy. Wiring direct to battery and running ground to blue wire connection blower blows great. HELP ITS HOTTT!
Thanks
Steve
