Hello JAEGERMAN,
It sounds to me like you need to have the system checked to leaks If that is not enough 134a in the system the compressor is not start up. Now if you have already do that and it is still not working then there is a Air Conditioner Amplifier That also starts the Compressor and will not start if it is bad. That controls the trucks idle and air conditioning compressor. if that is bad you may have to take it to a shop. But if you have not check the level in the system then you can do that yourself. Go to your nearest WalMart And buy a can of 134a with Sealant in the can and make sure you buy to one that has the system check gauge on the R134a fix it kit. Now what you want to do is to Open your hood on the truck and find the evaporator Its the Small Round a little bigger than a pop can should be stainless or aluminum having two lines running into it, You will see a Black Cap there and there may be two of them You want to use the on closest to the evaporator with the smaller fitting, Make sure the filler tube that comes with the R134 kit fits on the Valve by just taking off the valve cap and see if the tube fits on that fitting. Now what you want to do is go ahead and put the can and the tube together and go and start your truck up, turn your air conditioner on go out and Hook up the filler tube and can of 134 place on system and pull trigger on can of system seal and 134a let off and look at the gauge on can see if it reads Low or High Blue is usually good at the top of the blue. Just read the can and directions it fairly simple and I think You will find its low and need to be filled with the 134a and sealer so just go ahead pull trigger holding can upside down and let off few seconds until filled your compressor will start to turn on and off until system is up to full an hopefully it will seal it up and she will be working again, JAEGERMAN Hope that help you out Thanks for using Fix Ya and I am Bear001

Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

Testimonial: "You were absolutely correct. Low coolant level. Put in some 50/50 and we're nice and toasty now, but need to find out why coolant was so low. Thanks."

May want to look at replacing the wiper circuit board.It is located on the firewall adjacent to the wiper motor and has a some what square black cover with 3 torx screws and wireing harness pluged into the side.We had a truck that every time you washed it the wipers would stay on until it dryed out.You can try removing it and spaying it down with contact cleaner just watch the brease on the two contact tips.Well hope this helps.

I have a 2005 GMC Sierra regular cab. 4.3 v6 The heater has only been blowing cold air. Checked coolant and replaced the thermostat. No change. AC worked fine this summer. Heat worked fine last...


sounds like you have a bad temperature door actuator. This is a motor that connects to the door and uses inputs from the sensor in itself and the heater control module to open the door from hot to cold. I does take some knowledge on recalibrating this actuator and installing it. if it isn't install correctly it could damage the new part, so just take care

I just replaced the O2 sensor behind the cat on the passenger side. I was told to check the fuse as well. The truck is a 2006 GMC Sierra 2500 HD. I have no idea what fuse needs to be checked. I can't...


there isn't a seperate fuse for the o2 sensors as such, they are controlled by the PCM. The fuses are listed on the inside of the box under the hood.

I have a 2005 Gmc Sierra. The fan doesnt work anymore and I checked the fuse and its fine. How hard is it to replace the relay?


When you say fan I assume that you are talking about the heater fan?? The fuse and relay are usually plug in modules. Fuses are usually under the dash and relays and some fuses are under the hood in a large black box on top of the drivers side fender. A description of fuses and relays is on the inside of the lid that you take off. If replacing them doesn't work then time for a new fan.

When I turn on the heating system of the car not work is not sending hot air inside the car.


You don't say if the fan is working. If not, check the fuse. If the fuse is okay, check the switch and fan motor to be certain they are okay. If the fan is working, and still no heat (blows cold air), there is something blocking hot water from getting to the heater core. I hope this gives you some help to isolate where your problem is.

A/C and Heater will not blow air..


Blower motor resistor is most common ($20-$70) it controls the blower motor fan and speeds or fan relay fuse (usually under the hood) If it's not either then the blower itself is bad. You can pull the motor and apply 12volts to it to test, if it spins then the resistor.

Gmc sierra blower switch


last place to look is the resistor block located in the duct work for the blower (fan). it should have a wiring plug going to it and be held in by a couple screws. look on the passenger side near the fan itself.
