Question about 1999 Chevrolet Silverado 1500

1 Answer

1995 Chevy Silverado 4X4 cold air blows through floor vent

It is winter and the heater is turned on to maximum, lots of heat, everywhere except for passenger floor vent, which is icy cold. Had disconnected air conditioner so it would not run during winter. Should this disconnection cause the problem? Is it possible that it may cause the magnetic clutch for the air conditioner to stay on constantly? Or, is it possible that the vent stays open, allowing outside cold air to come in, when this air conditioner is disconnected?

    We re-connected the air conditioner and there is no more problem!  Thanks anyways!

    The air conditioner regulator in my primera wouldn't work, except I turn it to the highest. What could be the cause of this problem?

None of the above, the vent door is stuck inthe open position most probable cause is vacum leak look closer to your fire wall and you will see a very thin vacum hose going into the vehice which seems to be unpluged!!

My 2006 Ram 2500 Diesel cab heater blows cold are out the driver's side vents and hot air out the passenger side. I can't get the cab warm in the winter unless I place the heater in recircula


CHECK all the vent hoses, are they connected, no ob strucctions, when the last time you replaced the cabin air filter ? do you have one? look @ your owners manual, also, you may need to have several heater controls, or other control on as well, see owners manual, anything fall into the defroster vents ? replace thermostat @ engine. see how this works for you, good luck

your heater core is possibly stopped up if there has been a radiator leak and stop leak has been poured its definetly clogged or could be a faulty thermostat

Driver's side defroster and heater vents blow cold air but the passenger side blows hot. Both sides should blow hot The temp is set any temp and it still does the same thing. It is winter so I don't know...


The doors that open and close in the heater control unit are ran by motors. It sounds like a motor has quit in yours. When turning on the defrosters the motor closes the door to the heat for the floor

1995 Chevy k1500 heater problems.


For a 95 Chevy Silverado....I replaced the Blend Door Actuator on the passenger side. Just behind the slide out cup holder. Yo ucan acces easily by removing the ash tray piece and the glove box....Or just the glove box and work like hell to get a socket in a tight place.

There are 2 actuators....one controlling the (Mode and Temp 89018681) and the other the (Air Inlet 89018367). I called the dealer and the parts were 85-125. I got it From TBA Auto (local store) for 39.00. A 20 min job at most.
