Both "blower" fuses are fed by the ignition switch. If there is no power to those fuses than the switch is the likely problem.

2009 buick lucerne, heater/ac fan intermittent working, then quit. Have already replaced climate control panel, blower resistor and blower motor. Still nothing. Anyone?

My Lesabre did that and I am not sure how my mechanic did it but he said it would cost an arm and leg to repair it so he hooked up a separate switch under the dash and everything worked after that. a seventy five dollar fix is better than three hundred. See if your mechanic has an idea. He said the off and on part of the automatic switch was not working but after he put an off and on switch in the line the climate control worked.

No air in front but i have air in rear is there a belt in front ??

Can you hear the front ac/heater fan? They use the same AC compressor so that should be okay. The fan switches fail quite often on those. That controls how much air is pushed by the fan for AC, heat and defrost. The switch is attached to the fan knob on the dash.

Cooling fan will not turn on

The cooling fan is controlled by sensors in the cooling system so providing that you can move the fan blades easily and you have current getting to them I would be having a code reading to check for failing sensors. As to the a/c problem the compressor operation is controlled by 3 switches 1 switch is the heater fan must be on as well as the ac switch --2 is a switch that turns the compressor off if the head pressure is excessive and 3 is a low pressure switch that turns the compressor off if the pressure is too low (no gas). have a ac mechanic check out the system for leaks

Where is the AC sensor in 2005 Jaguar S Type located

the water heater control valves are front right down low behind the radiator and are electricaly operated ,the AC pipe that runs under the engine but above the sub frame could be corroded out as this is a common fault with these cars ,also the electrical solonoids that shut off the heaters can corrode up as well but i have known them to stick open.

Have 97 honda accord 2.7 i've done everything, relays, fuses, temp sensors, radiator, jumped the fans with direct wire to battery, work fine, tried to run ac see what it would do but nothing ar all...

i am confused you have not mentioned your problem but it sounds like your engine cooling fan is not working? if so try replacing the cooling temp sending unit located on or near the thermostat housing. in fact disconnect it while engine is running and it should turn fan on in a few seconds.goodluck

I am assuming you are talking about the ac heater fan? You need a new fan speed resistor, I think your mechanic is confused and this you are talking about the engine cooling fan? Let me kno please rate

I have numerous proglems. I have a 2000 intrique. The right back signal light blinks very fast, doesn't work in the front. The ac blower works fine but blows warm air.A mechanic , someone my hysband...

Your rear turn signal flashes fast because the front is not working. Most likely you have a burnt out bulb in the front. If your A/C compressor can be turned over by hand and doesn't lock up or make any clanking sounds it's probably alright. The compressor will not run if the system is low on refrigerant. If you're having problems with the A/C and heater controls, that would be the first ting to repair. It doesn't sound at all like any electrical problems.

Cruse control

Does your blower fan work on your heater/ac or your rear defrost work it could be the igniton switch were you put the key in. Turn the car on and off several times once you notice the cruise will not work and see if it starts to work if it does than it is the ignition switch this just happen to my 2003 century.
