I have a 1975 k5 blazer and it blows cold air it worked fine last year but now it only blows cold air even on the defrost setting what can the problem be and how can I fix it?


A vent flap actuator probably needs to be replaced. It's what moves your vent flaps from heat to A/C or to plain "vent air" when you change settings.

The discussion in the link includes vent flap actuators. Unfortunately, they also include the infamous no low speed fan problem too.

Cannot get any air from dash vents while defrost and floor vents work fine...

Your particular actuator will be a different one than they found.
They're all a absolute pain to get at because they can be well buried in the dash. I would start looking under the dash on the passenger side, that's where most of the air control is. Cannot get any air from dash vents while defrost and floor vents work fine...

The right side of vehical puts out cold air and the left hot air when I have the heater on


The heater vents have mechanical flaps that open and close when you switch the setting from hot to cold air. Sounds like one of those flaps might of jammed in the cold air or the cable that is attached to flap has come off.

Douglass, Your A/C may have lost it's programming, blend door actuator could be faulty or A/C could be low on refrigerant. You may have to take in and have a good Tech. diagnose and estimate repair.

A/c only blowes hot air in all temp settings,Even in the automatic mode.


Gday mate,geoff here, what i have found in the past is that as most vehcles have the heater on all the time and the temperature from it is controled via a air flap the opens and closes, check list, is there leaves , what-not trapping the flap, vents, are the vacuum hoses contecting the systems under the dash connected and operating, is the A/C actually coming on ? is there an A/C fault under the hood? hope this starts the procss fro you,geoff.

1998 Chevy S10 pickup air condition compres is on instead of heat


First be sure that you do not have the controls set to defrost the windows since on just about all vehicles nowadays with the controls set that way the air conditioner will be turned on...even if it is not so warm outside. So...be sure that you do not have any of the controls set to defrost and that the heater is turned all the way on.

It sounds like though that the control for the vents is not operating properly. This is a combination of mechanical movements of the vent flaps and small "air motors" that operate the flaps. These air units are controlled by air vacuum taken from the engine compartment through tiny hoses. If the hoses get cracks, holes or come loose from their fittings then your vents will not move correctly so it is a matter of looking and tracing each one of the hoses to make sure they are fastened correctly, have not come loose and are not cracked or leaking. The problem can even be in the engine compartment where the hose(s) connect to the engine vacuum system...so it will take lots of looking carefully with flashlights etc....good luck.

Passenger side blows hot air when front control set to Air


you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.

2001 Suzuki XL-7. Heater blows hot one side, cold the other.


No ductwork [to the lower vents] under the dash. They are part of the heater core / blower housing is integrated (all one piece).

After reviewing shop manual, we suspect that one of the three damper flaps is not positioning correctly; or debris has blocked one side (which makes more sense given the symptoms).

We're waiting for the temperatures to get back in the plus numbers to check out the physical arrangement.
