More than likely the AC system has no refrigerant charge in it. have it checked for proper pressures by a local shop. If it is low fix the source of the leak and then you will need to convert it to R134 from the R!2 used in the system, R12 is longer made worldwide because it destroys the Ozone layer in the earths atmosphere.

SOURCE: diagram bypass heater cord on 2001 ford expedition eddie bauer

the heater bypass is quite simple, if you look at the firewall you will see two medium sized coolant lines, remove them from the firewall and link them together using a proper sized tube, you can purchase a kit at a parts store quite cheaply

What is the minimum compression for a ford 390 engine.


No idea or where to find that

I had a 390 in a 1967 T-Bird

I kept no record on that, but think
I had about 160 lbs,somewhat less
than my 365 Vette

Today you forget compression & do cylinder
leak down testing & compression is what it is

Heater Hose Replacement


Well, I am sure that you do not want to hear this, but to get to the heater core you must remove the passenger fender liner. Most mechanics would cut a hole in the fender liner and then weld it back up once the job was done just to make the job quicker. This is one of those "Better Ideas" that Ford is famous for.

Need vacum diagram for the 1967 ford ltd. Heater/air conditioner switch will not change from one to the other


If vacuum operated, you will have a single vacuum line from the engine through the firewall, and to the switch. From there, the vacuum will be routed to however many controls the vacuum operates-about 4 to 8, typically. First make sure the line to the switch has vacuum and has not been disconnected. If you have vacuum to the switch, check the little vacuum control canisters around the heater case for proper operation-the diaphragm in the canisters may be bad.
Sorry, I've never seen a diagram for the heater controls.

NOT GETTING ANY HEAT AT ALL, REPLACED WATER PUMP, THERMOSTAT, VALVE TAP ON HEATER HOSE CHECKED VACUM ALL WORKS CAR RUNS WELL NO OVERHEAT PROBS, AND HEATER CORE FLOWING WELL. JUST NO HEAT FROM HEATER AT ALL


Make sure the blower runs, then make sure the heat and ventilation control doors move as they should. If you have hot coolant flowing through the heater core, air flow through the core, and appropriate air flow path, then you will have heat.

There are fuses on top off the headlight switch.

There is a button on the side off the switch housing you push to remove the knob and handle. Then remove switch from dash for access.

They are there because they did not blow very often.

F250 a/c not working at 60 mph. works fine at low speeds.


The belt could be loose.
The fan clutch could not be keeping up at high speeds to keep the system cool
I would have the cooling fan checked.

No heat! changed fluid, thermostat. Was going to check control valve but don't know where it is. if that is not the prob should I change the core


This problem is one i have encountered on a number of vehicle not just your brand. The problem seams to be in the controls switches and sending units. you have change lot of parts but did you check to see if you had flow through the heater core.Remove the heater hose's from the engine going to the fire wall. This is not precise in how you get the hoses off, however you do it? Once the hoes are off take a garden hose and try to run water throught the heater core. If you do not have a flow you need to find the closed valve. You may need to block off the hoses to the engine so you can run it for a vacume system. You may need to cut and put splices in the water hoses to do this. As a lot of engines you can not get to the end of the hoses.
This is not a simple fix as you would think. As i have found the heater hoses are getting warm or hot with the engine running but it is still cold inside the car. The word is no water flow no heat and if you have flow you have a vent door stuck closed. Air conditioner controls can have effect also. you may also may need to check the water pump out put to the heater core. This needs to be done with all the anitfreeze removed so as not to lose it on the ground. If you do remove the anitfreeze you can check the heater core flow by only removing 1 (one ) hose for the firewall to the heater. if you have hose off remember to put the garden hose in the radiator with it one as not to over heat the engine while it is running. you had heat before it a matter of tracking down where the flow has stop or the cause like a bad switch, broken wire or vacume hose.
good luck
