1998F-150 4x4
hey people i was just wondering if anyone can answer a question for me. I am using my fan and i am not getting much air flow at low speeds. The only real air flow i get is at high speed.
The question is does anyone know if the truck has a cabin air filter that might be plugged which is slowing flow down?
Thanks for the replies

the blower motor in the F150 is 4 speeds... medium, slow, slower, and almost off.. You dont get much air flow at the bottom speed and not much better on #2. If you want air when under 30 MPH, you go with #3 speed.. #4 is good., but kind of noisy.

Perhaps that's how "the blower motor in the F150" you own works.
My "98F-150 4x4" provides excellent air flow. Once cooled down the lowest 2 speeds generally give plenty of air flow for AC in FL Summer (or for heat in FL Winter). The high speed Max AC setting feels like a chilly leaf blower.
No, there's no "cabin air filter", but if using AC the evaporator is subject to trapping debris that "might be plugged which is slowing flow down".

Max AC is recirc air, so 'speed 1' at faster cruising speeds will feel like 'speed 1', because the outside inlet is closed off.

Edited my post to clarify for Podaso.
My reading of piperacer's: "at low speeds..at high speed" may have been wrong, but I took him to mean "low" & "high" fan speeds-NOT different forward speeds/MPH.
My AC provides excellent air flow, once cooled after parking in FL Summer sun, while "cruising" around town using the 2 lowest positions on the blower switch. That is, averaging under 30 MPH, in 35 MPH speed limits, waiting for traffic lights, etc.
Sorry about "Max AC" another of my vehicles provides a special extra high fan speed only in that position.
