Heating system only blows out hot air through the vents

Even with the A/C on, hot air continues to come out of the vents as if the temp guage was turn up as hot as it will get. Couldn't find any blown fuses. Is there a separate thermostat, other than the engine? Could the knob be stuck?

I would look at the air blend doors first, it sound like they are not working or your control in the dash is not working send a signal to them. they work by changing the air from hot to cold or in between.

The airbag in your vehicle is an important safety device, and the airbag module ensures the proper functioning of your vehicle's air bag. If this module is not functioning properly, your airbag may not deploy during a crash. When there is a malfunction, your airbag module warning light will illuminate on your vehicle's dash. You will need to have the airbag assembly checked out by a qualified mechanic, but once that is done, you can reset the warning light and airbag module unit. If you've never done this type of job before, it should only take you 5 minutes.

    • 1 Open the hood and loosen the retaining nut on the negative cable wire cable clamp using a socket wrench.
    • 2 Slide the cable clamp off the negative battery terminal.
    • 3 Wait 3 to 5 seconds and reconnect the battery terminal. Tighten the retaining nut using a socket wrench. Once the power is restored, the airbag module should be reset.
    • 4 Verify that the module has been reset by turning the ignition key to the "II" position and checking to make sure that the airbag light does not illuminate.

Bleeding Brakes on a 2001 Silverado Z71

Does anyone know how to bleed the brakes on a 2001 sivlerado i have worked on brakes before but i am having difficulty bleeding this truck do i have to bleed the abs junction box under the truck?

Tony,

When bleeding brakes after the system has been opened for service (you didn't say if you were doing any work on the master cylinder) you should start with the farthest wheel away from the master cylinder, which is the righ rear. Fill the master cylinder, then have an assitant "pump up" the brake pedal. Tell them to hold it down firmly, then open the bleeder on the wheel cylinder(s). Do not release the brake pedal until you have closed the bleeder valve again. You'll know when the air is out - there won't be any more bubbles. Since this vehicle is 2001, this would be a great opportunity to flush the system. Just make sure you have enough brake fluid (DOT 3 or 4, depending on your vehicle). Good luck!
