2004 F-150 Blower Question

[Cecil]

My blower has been working intermittently for the last couple weeks. I will be driving down the road and the whole fan and A/C unit will shut off. 10 minutes later it will come on for a few minutes then shut off again. Worked all day yesterday, and then this morning it does not.

Here is what I have tried

-Replaced resistor

-Replaced Relay switch (on fuse box under glove box)

-Put direct power to blower motor and works fine

-Unhooked battery for 30 min to allow computer to re-set.

Can anyone think of what else it might be other than the actual switch itself?

Automatic or manual HVAC?

When you say the whole thing shuts down, can you still change the mode (defrost, vent, floor), fresh/recirculate, and Temperature?

[Cecil]

Manual HVAC

When it shuts down, nothing works. No air comes out of the vents, the AC light goes off. I can turn the dials, but it doesnt change anything.

I'd pull the control head and look for burnt up/discolored connectors/wires.

[Cecil]

That was kind of my next step. Any trick to doing that?

Gulp alive! The only way to fish. I have my kids hooked on it as well. Out fished them once and now they won't go fishing without it.

If 4wandereyes sees this he will likely give you some help on pulling that out. I can't recall off hand without seeing it.

Thanks much!

To remove it, the instrument panel face comes off around the radio and heater controls, it just pops off, then when you get that off, you will see 4 screws holding it on. Just remove them, it comes right out.
