Sounds like you have a shorted power wire to ground in your heater circuit.

Would you advise taking the vehicle to an electrical wiring mechanic shop ? Or do tou hink its something you can do yourself ?
SeabeeMechanic Nov 22, 2016

I'm a mechanic by trade and can repair. Electrical is one of a few detailed oriented jobs in any vehicle. Specially now that electronics has come a long way.

If you have an understanding of how electricity works, and know your way around troubleshooting, go for it. If not, best you take it to a repair shop.

If you know how to disassemble your dashboard, where your heater switch is, try replacing it. If you go to a few online sites, you may find one for a reasonable price. If you are in the US, try a local junk yard. Or on line to rockauto.com and partsgeek.com or 1aauto.com

Finding a cooling fan relay under or in the dash for a 2004 impala that makes the fans run on high for a/c

Are you talking about the HEAT / AC blower motor , that makes that cool air blow on the inside passangers ? Or the fans that draw air through the radiator ?

Suzuki x4 2009 fan does not spin but when I turn air on it blows cold air.

Not sure which fan you mean. Engine cooling fan is different from heat/air blower fan.

2004 Chevy Silverado 2500HD ac stopped blowing we changed motor and resistor and still nothing we have cold air running when u drive down road but no pressure

I'm going to assume you have the manual control version. The relay in the resistor allows the fan to run on high and bypass the resistor circuits. There is a 40amp blower fuse for high speed and a 30amp fuse for the other speeds. The motor is grounded thru the resistor.
Do you have power and ground at the motor on any of the settings ? ?

Air conditioning problem

Air Conditioning problem

Ac is not blowing out cold air. You have to put gages on the system and it shows its has freon.Checked all fuses and relays. The two fans in engingine compartment do not come on when the ac is turned on but does when the engine gets hot. The compressor engages when turned on also.
If the magnetic clutch engages the compressor and still no cold air could be still low in freon or the HVAC unit.

Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?

I have a 2004 Chrysler Pacifica and my blower is blowing only cold air. The heat does not work.

Tenia, the most likely cause is that you are low on engine coolant. The coolant from the engine also runs through your heater coil. Check the coolant level when the engine is cool. There is a line in the coolant resevoir that says 'Cold Max'. Add the premixed coolant until you reach that line.

If that works, I would monitor the coolant level over the next few days. If it drops again, you likely have a coolant leak somewhere.

There is no heat or cold air blowing through the vents when turned on.There is cold air coming through when the car is travelling fast but there is absolutely nothing when the car slow right down or stops...

Sometimes this is caused buy a vacuum problem. It is not opening the door to let your air in at a slow speed. The doors are opening at high speed due to the air pressure from the outside air. Make sure that the fan is runnig by turning your ignition on but not starting the engine. Turn the fan on high and see if you can hear it. If the fan is running then take you car to a mechanic you trust and have them check the vacuum going to the door.

2004 Chevy Trailblazer, At first you could only get the air conditioning to switch on by turnning the vehicle off and switching over to AC. Now the AC will not come on and it is always blowing hot air out...

Could be your main blower motor resistor, mine would still run the fan even after shutting off the vehicle.(safari van) Had to unplug the resistor to stop the fan,it was near the blower under the hood. Bought a new one for about $45 bucks. Replaced it and all is fine. Might want to check relays first, sometimes they stick and need replacing.
Good luck.
