Question about 1999 Chevrolet Silverado 1500

1 Answer

Cabin air vents blow loud and weak?

The air, whether it be hot or cold (I have no problems changing between the two), blows very loud, especially on the highest setting. It blows significantly louder than would be expected. In addition, the outside front vents (the ones by the driver and passenger windows) blow significantly weaker than the inside front vents. However, none of the vents are blowing as well as they should. I have checked the cabin air filters, and that is not the cause. The loud noise that is made does come from underneath the glove compartment on the passenger side very close to that area though. Any thoughts?

Possibly the fresh air to re-circulation door is either binding or is broken.

i was a GM mechanic for many years, the problem you are having is one of your mode door actuators has gone bad, most of the time it is the actuator on the drivers side that causes the problems, i have seen this many times, sometimes you can take it to the dealer and they can hook the computer up to it and recalibrate it but most times it has to be replaced , it is located under the dash in the area above your gas pedal.

SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

You need to replace the drivers side temp actuator that is located on the left side of the HVAC box. It is retained by 3 screws and is fairly easy to replace.

The A/C is blowing cold air but why is the blower weak?


Check that you have the selector set to blow out the vents and not the defroster or the vents by the footwells. Does it sound loud like it should be blowing strong or is it weak? The selector 'doors' under the dash work off of engine vacuum lines. If they won't 'select' when you change the knobs, there may be a vacuum line leaking. Also, make sure the blower motor is not all clogged up with leaves and debris.

Only get cold air from heater


Check whether any hot water flows in the heater hoses which are located between the engine and the firewall .If you to have the feeling hot water and not hot air in the cabin means either you do have blocked Matrix,or the circulation flow valve stuck to cold flow.
* Start the engine first and leave it for 5 minutes running till get to temperature and then check *

On my wifes 2006 chrysler sebring air blows cold and hard in town once on the highway it seems to stop blowing hard , its still cold it gets loud like the air is blowing but , just not all out the vents


Do you live in a High Leaf Area? The Cabin Air Filter could be blocking the system. Additionally, there is a resistor that is common on Dodge's to go bad and cause the fan not to work properly.

My heater isn't blowing cold but my cold air conditioning is working. It does blow, just not warm. You may need to know that I recently had my radiator and water pump replaced. I had hoped these problems...


May have to 'flush' out the system, especially if the heater core has 2 hoses at the 'firewall' that are not getting hot when the engine is hot.

If the hoses are getting hot but it's cold inside the cabin, then it's a bad blend door actuator problem.

Good luck on this repair.

Why is all the air blowing through the defrost vent only


Either the door that controls the flap that either sends the air through the defrost or the regular outlet is stuck or not working. Some of them work off of a cable and others work from vacuum. Not sure which the ford escort uses but usually you are able to hear the flap move when you go from defrost to regular cabin vent. Or possibly the air duct hose has come off that sends the air through the cabin. Good Luck and hope this helped a little.
