Where is dash AC vacuum pump and vacuum lines on 2013 Thor ACE 29.2? Blower works only on defrost

SOURCE: vacuum diagram 1992 ford taurus

Well as far as knowing exactly which hose to put where i cant help. Other than tell you to buy a chiltons manual at advance auto. Now there is a box in the passenger side floor under the dash of your taurus. this box is actually where the flipper is that switches from floor, to vents, and of course your defroster. So you can reach up there manually and switch yours to defrost. Just turn your heater on and(blower motor) then look for the black box should be like one foot by 1 foot. There will be a little siver selector switch on the side of this box. Just flip this switch by hand and you will make your hot air go up to your defroster, also while you are under there, look for loose vacuum hoses, this is normally cause by children hitting these hoses with their feet and disconnecting them. So i am sure now that you know where to actually look you can fix this problem. Hope this helps ya

Replace the complete heater control vacuum line over the motor with rubber vacuum tubing.
The heater vacuum line connects on the drivers side of the engine halfway back on the intake manifold.Run the new line to the heater vac connection at the passenger side at the right front in the engine compartment.
I change 2 a week....this should be where your problem is.

Testimonial: "That took care of it. I did change from that small vacuum line to the large rubber and ran it up to a wire loom overhead so as not to get as hot."

Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

Testimonial: "Thanks!!!"

In the engine compartment, locate black vacuum hose that runs from brake booster check valve to intake manifold, there will be a small vacuum hose attached to check valve at the power brake booster check valve. This is the vacuum line going to the heater control unit,check the hose all the way to the firewall, repair any leaks you find. And that should take care of your problem.......GOOD LUCK
