Question about 1994 Ford Aerostar Extended

1 Answer

No power to all three (3) blower switches, rear defrost switch,

I'm having a problem with my van. No power to my three blower switches, rear defrost switch,turn signals,and back-up lights. They were working fine when I shut van off. I started to take the panel off to get to the fuse box, when they started again. I shut engine off and when I went out to start engine, they would not work.They either all work or none work.It seems that there is something common to all of them but do not know what it is

Check for a loose connection at that fuse panel you were playing with.
I'll check other ideas & get back to you, while you check that.

Why don't blower positions 1 through 3 work?


Because the first three speeds are not going through the same power feed configuration. You can check the speed switch but I do not think that is it. Kind of hard to fathom three contacts all going bad at same time.

Rather you might want to check the schematic and you might discover that the first three speeds of the blower go through a special circuit powered by your car's ignition switch!!! If that part of the ignition switch goes it affects your ac blower - and don't be surprised if your rear lights and some other stuff is not working also!!!!!

HOW DO I WIRE A TOGGLE SWITCH TO REAR DEFROST SWITCH. TOGGLE HAS 3 WIRES DEFROST HAS 6 WIRES?


You should not try to wire the switch to the actual switch harness, instead identity the relay that powers the defrost, because toggle switches are only to switch power on and off to a device.

E-150 van blower stuck on defrost mod will not let me turn off or go to a/c mod switch is fine turns ok, stuck on defrost mod you can turn the blower off and on but it will not let you chose any other...


You most likely have a vacuum leak in the climate control switch or elsewhere behind the switch. 75% of the time the climate control switch must be replaced, otherwise in the other 25% the vacuum leak must be found and sealed(if not in the switch) before normal operation of the unit will occur.

Front defrost blower wont turn on, rear works fine, what could it be?


Three possibilities:
1 the switch has failed and needs replaced. Test with a multi meter
2 The fan has died and needs replaced. test with a multi meter
3 There may be a fuse for it that has blown and needs replaced. Check all the other buttons and switches in the dash to see if there is anything else not working, this makes the fuse the most likely

95 jeep Cherokee heater wont work but rear window defrost still works need help please


Check the blower motor fro good connection, power and ground. Hot wire it to the battery and see if it runs. Check the blower fuse, relay, switch and resistor pack.
blower and rear defrost circuits are totally unrelated.

I am having a problem with the blower in my van. The blower still blows air in the rear of the vehical but not in the front. What could the problem be?


check the filters located behind a panel in the back of the glove box they should be cleaned at least once a year. if not plugged then check to see if the switch is changing from panel to floor to defrost ect. could be this selector switch.
