1999 wranglers heat only worked on high and now it won't work at all?
the 1999 wrangler's heat only worked on high,but now it don't work at all.
Why does heat fan on Toyota Solara only work on high?
You most likely have a bad blower motor resister.......
Why does the heater fan only work on the high position on a 2001 Chrysler Sebring?
The most common cause is a failed blower motor resistor.
Why does your heat only work when your car is moving?
The heat will also work when the car is turned on, but not moving. It uses heat from the engine.
What would cause the AC and heat to only work when switched to the high position?
AnswerYou have identified the problem when you state that it only works in the high position. Your switch has variable speeds, it contains resistors that control the speed of the fan, for both AC/Heat. These resistors are burned out/or the connector to the resistors has become unplugged. The resistors are located in different locations so please get your auto manual to locate there position, and verify there operation.Most cars have a simple blower motor resistor that provide the low-medium speeds. If it burns out the fan defaults to high speed - the most safe 'default'.Walk into any auto parts and tell them your car only blows high and they'll immediately know what you need.In most Ford vehicles this is a 10 minute, 2 screws procedure that most anyone can handle.
Why does my heat in my 1999 dodge caravan only work when you turn the heat on high?
a bad blower motor resistor heat normally used on medium and high medium usually burns out those speeds first till only high is left normally located right back under glove box on heater box/core line usually 20-40$
Why your ac fan blower work only on high position?
replace your blower motor resistor it is behind the glove box two 8mm bolts
Why does the switch for my 1990 Toyota Camry's air conditioner only work in the high position?
Blower resistor must not be functioning properly. It should be replaced
How do you find relationship between work and heat practically?
if only heat change is the only change then energy difference is the amount of work done.
Which describes the work done by the heat engine?
A heat engine converts heat energy into mechanical work. It operates by taking in heat from a high-temperature source, using it to do work, and then releasing the remaining heat to a low-temperature sink. The efficiency of a heat engine is the ratio of the useful work output to the heat input.
If my cab heat and ac fan only works on high setting is it bad relays resistors or motor?
AnswerI think it is the switch or the wires. Actually it would most likely be the resistor motor is shot, if the blower motor only blow on high there is no resistance thus it will only work on high.
Why does your 1999 Yukon heat only work on high?
If you are referring to the blower motor only working on the high speed setting, then the problem is the blower motor Resistor Pack is defective. Replace it. It can be the blower motor speed control switch but not likely.
