The clutch won't engage until you charge the system and will engage as soon as you get close to the correct pressure.

2001 Ford F250, have no heat, blows only cold air. Have changed heater core, thermostat is working properly. Have checked and tried everything it seems and still no heat.

Hi Shannon, IM AL the owner of Big As Auto Repair.

Shannon, it looks like you have ruled out the coolant side not heating properly with the thermostat replacement and coolant flow through the heater core because you replace it as well. Let's first make sure coolant is getting to the heater core. Here's an easy way to check this issue. Start the engine and drive it until completely warm then park and leave the engine running, open the hood and check each heater hose that is connected to the heater core at the firewall. If both hoses are equally hot then the coolant is getting to the core and working properly. If one is a lot cooler then the other then you could have a heater valve on the system "OR" a water pump flow issue. BUT, if they are equally hot, then you most like have a heater door issue inside a/c housing. If the heater door is not working properly and staying on the cold side you will not have heat. Lets stay in close contact buy you going to my auto-repair-website and work together. Just click on "CONTACT US" and I'll work with you until we resolve this issue.

Ac wont blow cool

check the actuator door on the heater and make sure it is opening an closing the door on the heater to transfer from heat to ac. It is a small motor attached to the heater and allows the ac to be directed to the vents.

Sable blows warm air temp guage stays on cold side

this may be a goofy question BUT do you mean flushed the radiator not the heater core. Heater core is on the firewall.
Check the hoses going into the heater core to be sure they are both hot after the car has reached running temp. This will let you know if you have a blocked heater core not radiator.
Just wondering?

Heatercore stop up needs fixing

Make sure it is the core and not the water valve. Disconnect the heater hoses and try to run a home water hose with city water to flow through the core. You may be able to backflush the core by alternately putting the city water pressure through either side of the core.

Before you try this, check to see if both heater hoses are equally hot when turned on. If they are equal, the problem is not the core but inside the dash flaps in the air ducts under the dash.

Heater blows cold air

Either the temperature blending door is stuck, the temperature control cable came loose from an anchor at the endof the cable jacket, or there is an air bubble in the heater core or heater core is clogged. Is the coolant mix adequate for your climate?

with the engine warm and running, are both heater hoses warm? If not, there is no flow. In one extreme case with one of my own vehicles I installed items that are called flushing tees in both hoses to purge the air out. Matk one hose on both side of the cut to distinguish it from the other, and check the ability of the heater core to allow coolant to glow through it. If you are above freezing, water from a garden hose is fine at low pressure. Otherwise you need to use regulated compressed air. If no flow- the problem was a clogged heater core replace core.

If heater core had decent flow thtough it, install one flushing tee per side- ideally in the middle of the hose so each can be held up to collect air from the bubble. With engine cold, start the engine with both tees capped. The one hose that leads off the water pump- crack open first tee until coolant flows. snug cap reasonably tightly. Then crack open the other tee, hold it as high as the hose will allow until coolant begins to flow. then snug cap.

At this point you should have heat if the control cables were all anchored, and doors/actuators opened and closed them correctly.

Replaced a/c compressor serviced with oil and 134a still blows hot air. 2001 galant 2.4 cyl

do you have a guage to check the low side pressure? if the low side pressure is less than 20 psi then you could have a bad expansion valve that is not letting the freon circulate. also check the controls to see if the heater works all the time. the air temp door may not be moving to the cold position.

Heat guage shows normal temperature but heater throws cold air. Problem gets a bit better as engine is reved.

The heater core could be plugged up. Try to flush the heater core out, or replace the heater core in order to fix it. Also, check the heater core for hotness at two 1" diameter tubes at the firewall. If they're hot, then the blend door may be causing the problem.

Good luck on this repair.

It is much more likely you are low on coolant or you have an air bubble trapped in the cooling system. You should bleed the cooling system to get any trapped air out and make sure it is full of coolant.

My 1990 Jeep Cherokee's engin temperature guage wont go above the minimum temperature unless it has been driving for about 30 minutes and even after it starts to slightly raise above that, i am still not...

your heater core may be clogged up. The temp of the inlet hose should be about the same as the outlet hose-under the hood. If one is signifcantly more hot then suspect a clogged heater core. You can try to back flush the heater core. Remove the heater hoses at the engine side- not the heater core side because the hose fittings are fragile. You want to blow through the hose that was cooler to the touch with light compressed air or water pressure. be sure to bleed air out of system. If water flowed freely through the heater core then you may have an issue with the blend door on your heater box, or heater control. Do not blow up the heater core! keep pressure below the psi rating of the radiator cap.

The slow acting of the temp gauge may indicate air in the cooling system. run the engine, heater on, with the radiator cap off to vent the system, doing this on an upsloped driveway will aid in venting the air.

My heater will not get warm

Check your collant level If your radiator is full then you can place carboard in from and over the lower third of the radiator to block the air flow. Watch your temp guage to be sure you don't over heat the engine. If it still does not heat up pproperly you can block more of the air flow as l;ong as the neging temp guage is not showing it running hot. If it runs too hot remove some of the carboard allowing more air flow. THe proimary reasom for the heater not putting out warm air is low coolant, blocked water flow to the heater core or a bad thgermostadt (wrong thermostadt; one that opens at too low of a temp, defective thermostadt trhat is blocked open or even a missing thermostadt. Regardles what you do just be sure to watch the temp guage as you can do serious damage to your engine if you overheat it too much. Again, be sure you have the radiator topped off properly before you start
