The first thing to check if there is any R134a in your a/c system... no pressure in it means the switch turned it off to protect the compressor

SOURCE: 1998 Mustang - AC blows only through Defrost vents

You probably have a vacuum leak on the passenger side. its a small plastic hose some times they come unpluged from the engine. or brake.

SOURCE: Temperature Control not working on 1999 Ford Explorer

Sounds like your temperature actuator is not moving or your temp door is broken. On max a-c ,coolant is shut off to your heater core allowing only cold air in.

SOURCE: 2002 Honda Odyssey fan only works at high speed. The A/C compress

Usually when the blower fan only operates on hi speed, its because of a failed blower motor resistor. You still have hi speed because on hi, the power going to the blower motor goes directly to it, as opposed to the lower speeds, when the power is routed through the resistor, thus lowering the voltage, which in turn lowers the speed of the fan. The resistor is usually located near the blower motor itself, under the hood back near the firewall.

SOURCE: 02 Jaguar S Type - Heater blowing cold air

Has the vehicle overheated recently, if not there is a failure of the Coolant from engine valve controller, that measures flow through the Heater Matrix. Come back with more, as necessary.

07 Saturn Aura XR The fan on the climate control is not working When I turn the temp up hot air slowly comes out of which vent is selected and cold air when i turn it down But the fan will not work


Your Blower Control Module/ Blower resistor is probably bad. It controls fan speeds. The blower motor itself could be bad, I doubt it unless it was making noise previously. The blower resistor is under the passenger side dash.

07 Saturn vue. My ac isn't blowing cold and my controller for the blower doesn't always work on the selected speed setting but comes on later.


Could be the AC needs recharging. Low pressure causes all sorts of things. Get an agent/shop to check and recharge if necc.

Sentra AC


There's a 10amp fuse that powers the ac clutch relay and compressor. There are 15amp fuses that power the blower motor and the ac control switch. All of those fuses get power from the key switch. The resistor and fan switch provide the ground circuit for the blower motor.
I would want to know if those fuses are getting power, and if the control panel is working. You should be able to ground the blower motor and make it run on high, and that should not have any effect on if the ac compressor is running or not.
It could be a key switch problem in that the circuit is not strong enough to handle the load from the blower and the compressor at the same time.

Ac problems


well,i'm in the same boat."fixed income"... BUT! if you have to keep the car instead of takin out a cheap car loan like i had to. I can tell ya, if the c-box isn't getting continuity,[check on firewall] on olds pre 2001. If you are, than the compresser needs to be purged,there is an air bubble in there that's a pain in the **** to get out. "GOOD LUCK''

04 Saturn vue compressor turns off when fan is set to 3 or 4


The problem is the blower motor speed control resistor, it is located near the blower motor in the housing. I exchanged mine and it works like a charm now.

My Saturn ac and heat quit working. doesn't blow anything on no speeds. where is my blower motor and do i have to take my dash apart?


Its most likely going to be the blower motor resistor or the blower relay. Usually the relay for the horn is the same so you can swap them; check that first. If that is to no avail then pick up a chiltons manual and locate your resistor. Good luck!!

AC only works on settings 3 & 5


souns like a bad blower resistor.the resistor controls the different speeds.sometimes every speed except the highest will stop working.the blower resistor is almost always near the blower motor.

= 07 ford five hundred ac problems


First off,is the ac compressor turning?If so are the large line,near where you put freon in,cold?If the low side lines(large lines)are cold and sweating,and the evaporator box is dripping water on the ground,then the ac is most likely fine.There is a temp door in the ac blower box,that moves for hot,or cold when you select these comfort levels.This door is most likely controlled by a actuator motor.This motor is most likely bad.If it is control by vacuum,look for a broken vacuum hose,or one that has come loose under hood.

2008 saturn vue when ac or heater is on the fan blows hard then completly shuts off then comes back on on low then blows hard again all without touching the knob


You have a problem with the heater blower speed controller, they act this way just before they stop working completely.
