heater 97 F150 Sign In

The heater on my 97 Ford F150 blows air but it is not warm. The garage says the heater core is clogged and the water pump is pumping weakly. Can a water pump operate weakly or is it a matter of pumping or not pumping? Does the dash have to be removed to access the heater core on a 97 F150? Thanks.

The impeller of a water pump (usually metal) pumps if it spins and I've never seen one quit or weaken. It could break I suppose but you would have lots more problems. I would flush the heater core forward and back and see how much junk you can get out of there. Most of the time that's enough. If there's almost no flow it probably does need to be replaced and flush out the whole system.

There sometimes are water flow controls on the input side of heaters for temp control and some may use a restrictor in the hose unseen with just a 1/4" hole to control the water flow so it doesn't put too much pressure on the core itself at high RPM.

Telltale of it being plugged up would be seen just looking in the radiator cap and see if the fins of the radiator look nice and clean. If there's evidence there the core would be a weaker link.

If there is a water flow shut off to allow for A/C to work better it does have to be checked that it opens up for heat request,
