Heat not working; my blower comes on but its not hot air, any ideas?


The temperature blend door is stuck on the A/C side ! Do you hear a clicking noise behind the dash ? Has an electrical controlled actuator that switches a door inside heater - A/C box from A/C to Heat . So the blower is blowing air over the A/C evaporator core all the time , not switching !

What part controls switching air/heat from defrost to bi-level to floor & where is it located?


In the attached drawing, Part 32 moves Part 26 to direct the air flow to the desired locations. It uses vacuum to operate. The actuator may be bad or the vacuum hose my have come loose when the heater core was changed. With the car running but the blower off stick your head up under the dash on the passenger side and see if you hear a hissing sound. If so it's probably just a vacuum hose come off.

Why does my heater only blow hot air?


if only blows hot from defrost location only, then there is a vaccum leak from intake manifold to the selector switch. or the vaccum selector switch is defective. if it is a electric selector switch then the mode door is broken, common issue. when the truck if first started, is there a repetive clicking noise? if so then it would be the mode door being broken, warrenting having to remove the dash and recovering of the air conditioning refridgerent, or freon, r-12, or r-134a as this year is R-134a, draining coolant as heatercore needs removed, and removing the entire heating and airconditioning unit, located behind dash on passanger side, disasembling and replacing door. if clicking noise is pressent and time and money, and certified air conditioning mechanic not available, then finding the mode door actuator, or electric motor that turns the door, and unplugging it will cause the noise to stop, but forever have no airconditioning, as default location is defrost. if able to select from defrost to panel or floor location but heat only, then blend door is broke. i believe mode and blend door are same part number, but might not.
also check for recalls and tsb's, or technical service bullitions, as might help fix it. recalls are free, and tsb's are only to help you diagnose the problem, and you would have to pay to have fixed or fix yourself, but having to evacuate and recharge air conditioning system and haveing to have the special tools to remove ac lines it may be a job best suited for a professional.

Circuit unit behind the ac controls


sounds like your blower motor has stopped working check for power going to the blower system if you have power the blower is probably bad the concern is the lack of a fuse blowing or a breaker not cycling you may have a harness problem sometimes a low grade short will heat up wires then melt them together causing a multisystem failure even though a fuse or breaker didn't blow check you harness

Air Conditioning only works during winter and heat only works during summer!


Miss Kristin, your situation sounds more like the air flow blend doors/flaps under dash are operating, but incorrectly. All these vehicles temperature changes are actuated by vacuum from the running engine. In your case it's possible a vacuum line has become disconnected from the blend switch behind the lever or the 2 heat and a/c hoses have become switched. Either way, I believe it must be in the vacuum lines under dash, or possibly no vacuum at all to the blend switch because the main hose from the engine has become disconnected or is broken. Best of luck on this luv.

No heat or cold air will come out of my2004 Mitsubishi Galant. I took off the dash panel behind the glove box to get to the Blend Door Motor, but after turning the air from hot to cold at various speeds,...


Does the air blows through the dash board vents. Does the selector is functional, that means you can force the air stream through wind shield, or vents or down to the legs. If these things are OKthen check CONTROL PANEL.
Remove the trim plate surrounding the center instrument panel. Detach the electrical connectors and remove the control panel.

My 2004 silverado will be blowing nice cold air from the air conditioning and suddenly thedrivers side will switch to hot. Shutting off the engine wil "reset" it, but only for a while .


there is a common problem with these trucks, but cannot guarantee without actually checking the wiring.

there is a part of your climate control system called a blower motor resistor. this is what controls your fan speed. it is located under the dash on the passenger side, long flat connector, inserts into the ductwork behind the blower motor. this part corrodes as a result of condensation forming in the system, causing resistance and high heat issues. under certain conditions, the heat from this can actually begin to melt the wiring harness going to the resistor, causing power to back feed where it doesnt belong, resulting in unpredictable heating and air conditioning operation, such as yours. it can also sometimes give you an intermittent burning / melting plastic smell.

the harness and resistor may need to be replaced. the harness is available from your local dealer. in my area they retail for around the $170 area, but the price my vary. the resistor is available at any local parts store. the repair connector harness comes with the necessary connectors, all you need to do this job yourself is some wire strippers and a lighter for the shrink tube connectors, along with a socket to remove the resistor - usually a 7/32". again, this is something that is a common failure, which SOMETIMES exibits your symptoms. a visual inspection of the harness will be telling, and give the components a sniff and smell for any burnt odor indicated. good luck!

yes there is a procedure,but no short cut in removal of dash board.but my advised is that pleased contact a perfect electrician to remove it safely because of the electrical wires.

Loud noise from under the dash, ac/heater area. No cool air 97 li


If this noise is a clicking sound and is coming from the front center of the dash, then it may be the blender door motor which will require removal of the dash to replace it. It will keep the door from switching from heat to a/c. Does the odor smell like you have a freon leak in your a/c evaporator core or does it smell like a rat stuck in your heater and a/c ducts?

No air flow through the rear vents with ac or heat on high


make sure the control knob on the dash is on "RR". This lets the driver control all the vents in the back. The heat only comes out of the floor vents, if you have the knob on the blue dots that represents the air conditioning in which the cool air will come out of the vents up above in the back. There is also an area on the control knob on the dash where you can turn the knob to shut the heat and air conditioning off. If the knob is in this position then you can control everything with the knob up above the seat right behind the driver's seat.

98 Lincoln TC,Cold starts fine ,runs good until warm, then shuts off. No codes,Cranks ok, have spark, PATS ok. No fuel pressure, cant hear fuel pump prime,New Fuel relay. jumped fuel pump - works. I do not hear fuel pump prime up, do not have fuel gauge, but pressing on valve in fuel rail- no pressurized fuel. Fuel regulator seems ok, not leaking / vacuum line dry as a bone. If I let it set for 15 min , it will start up again, but for a few minutes then dies out. If I let it set overnight it starts up perfectly and runs until operating temp is reached then stalls/stumbles, and shuts down. Vacuum is good while cranking, even with no start, Checked Inertia switch in trunk, it is not tripped. I have seen Ford TSB summaries' that mention issues like this , but I am not able to see to description. A point to add, the MAF sensor was cleaned, then I decided to replace it and did not make a difference. I do not have any stored codes, and the PATS is working fine, typical 2 second flash from and once key is inserted a 3 second steady light, then disappears. I have seen the TSB mentioning C103 Connector, it looks fine, I swapped out fuel pump relay with ac relay, still no difference.mention of wires around battery, do not know where to start. in dash service engine light and odometer is normal, seen other posts the say they only have lines, but mine is ok. the start of all of this , I washed engine with regular garden hose, ( not using pressure washer).also in the mean time, rear window defroster stopped working as well, can not say for same reason, but a mention.My problem started after washing engine. this is one of four Panther platform vehicles I owned with exact 4.6l w code engine, which I rinced down before. The only sensor I can think of is Oil pressure , or a corroded wire
