The dash fan/blower stopped working. Is there any relay or fuse to check?
Does it work on any speed setting? Our wiring diagram has a 30 breaker "A/C Evap Blower" #340 with red wire with 121 identification. Always check ground connection.
No, doesn't work at any speed or setting.
It appears that all the switches work except the fan switch
Ac on/off - fan at rear ac condenser turns on
Blend /recirc- the flaps move
Dash/floor/def mode- flaps move
There is power to the fan switch. Blower does not come on.
Have you checked for power at the fan motor?
The ground may run down to a body/frame tube under the hood with a sheet metal screw . RE ground all of the green and white lines that end there .
Is there any power coming out of the switch?
Can you jump from the power in to one of the legs out to see if the motor will run?
Go around the switch.
Haven't opened up the metal box to get it the motor yet.
On my 280 there is a relay that determines the speed of the fan by how much of the 12V's is selected.
