Blower motor relay went bad

Went to fill the fresh water tank at a friends yesterday(we have well water). Not one minute after turning the a/c on the fan just stopped dead. Figured I blew the fuse, no luck fuse was good. Figured this was gonna be fun. Checked for power at the blower, none. Jumpered the blower to make sure it works when power is applied, yup works great. Checked the resistor pack, that's fine. The manual has all the fuses listed and 3 relays none of which were for the blower motor so I thought maybe there was no relay. Pulled the dash apart the check the fan switch and no power to the switch either so I figured there had to be a relay. Found 2 other relays under the hood on the driver's side. Voila first one was the right one, plug in a standby relay and the fan fired right up. At least it happened now and not when we were leaving for 2 weeks later this month.
I guess the moral is check fuse AND relay first before taking a bunch of other stuff apart.

If it won't budge, hit it harder or get a bigger hammer.

location of relay?

I have the same exact problem with my 1995 E-350. I can't find the blower relay. Exactly which one is it? Thanks in advance.

Found this on the Ford Forum

There are five relays (including the blower relay) on a bracket between the driver's side battery and the headlights. Had to remove the battery to see the mounting bracket, which hides the relays. The bracket unscrews with a 1/4" wrench - remove it and the relays can be removed.

Found it. just where you said. Did not have to remove battery. Advance Part Number is R3189. ($18.99) Ford OEM: FOAB-14B194-DC. Identical one beside it I believe is a relay for the damper on the defrost/vent/floor ducts.
