I Can't Get Heat To Come Out To The Floor Only . It Will Come Out Every Where Else But There. I Have Found Sites That Say It Could Be An Actuartor Or A Mode Door But Dosen't Say How To Check?
My Feet And Toes Can Use Some Help With This Problem.
Thanks For Any Help

Check the supply hoses in the engine compartment for temp. Are both of the hoses hot. The coolant return heater hose should be slightly cooler than the coolant supply heater hose. If the return hose is much cooler than the supply hose, there is engine coolant flow obstruction in the cooling system. Possibly a kinked hose. If there is not a marked difference then you may have a blown diode in the wiring harness that is preventing the blend door from properly routing. Do you have any codes.
