You will have two fans, one fan blows out the rear of the unit that cools the condenser soil, one blows out the front across the evaporator that blows the cold air out into the room. Some window a/c's have whats called a squirrel cage fan assy. that has one motor that runs both fans. So you either have one bad fan motor (the evap fan motor) or you have a bad fan blade that has fallen off the shaft. Also check the filter see if it is clean.

I have a RUUD gas pack unit.....when you turn on the heat, the blower does not blow any air out of the vents while on "auto". If you put it on "on" it blows cold air out of the vents. What is wrong?


Sounds like the thermostat is hooked up wrong. If the ac doesnt work right its in the thermostat programming or the wiring. Hope this helps good luck

99 GMC Sierra 4.8 1/2 ton 2 wheel drive new body style ac does not blow cold air from the front vents on the dash? Still get some cold air from bottom by floor vents,


if both vents are blowing air in general then you may need to get your air conditioner recharged, but if the front vents aren't blowing at all then you may just have a jammed vent flap and you can fix that from under the hood next to the blower motor. check you rowners maual for the exact location

The air conditioning does not blow through front vents but through windshield vents, what is the problem?


This is a common problem on all Astro/Safari vans. The problem is a leak in the vaccum lines that control the vaccum switch responsible for changing air direction from the defrosters, dash vents, floor vents..etc.
Many of the problems that plaque the Astro/Sarfari vans and many other "Mini-Vans" is the build up of excess heat in the engine compartment. It\'s a tight place to put a V6-4.3 Vortec engine and the heat generated bounces back and cooks everything on the engine (coils, modules, sensors, wiring, and of course plastic vaccum hoses). No need to mess with your switches or anything behind the dash -- replace those thin plastic vaccum hoses to operate the vaccum switch (located just below the A/C canisters, to the right of the heater/ac blower housing) and your dash switches will magically send heated or cooled air where you want it.

Blower Turns off if ac unit comes on. No air coming through vents


This only could 1--2 things, a bad circuit board fan relay or bad thermostat. To check for bad thermostat, take off the front cover to reveal the 4-wire terminial and jump the red-wire (power)-cool,(yellow -y or blue)--- green--fan white-(heat)..........red to yellow-or y=cool. Thank-you-very-much!
