There is a black vacuum hose in back of the glove box toward the top connected to a gray hose about 1/8 thick.You need to check to see if there is vacumm there.If yes then you need to take the bolts off to be able to tip the dash back enough to see all the vacuum hoses.Make sure they are all connected.It was alot of bolts but its is the best way.I had a hose off going to one of the acuator doors.Glued it back on and works great

Just had the same problem. It was a broken vacuum line on top of the engine. Check all vacuum hoses, and especially the one that goes to your pot. You should hear it hissing when the engine is running. If not, wiggle them around until you find one. Let me know how it goes.

    There is a black vacuum pot bolted to your hood on the drivers side. Make sure the vacuum hose is still on it.

1998 Blazer A/C blows hot air.When I turn on the air conditioner it does not click. However, hot air still comes out of the vents instead of cold.

You need to recharge your a/C in the short term to get it going again. An auto parts can sell you a recharge kit for something like $30-50. if it stops working again your a/C system had a leak somewhere and you need to get that checked out by a shop or you can inject a uv dye and find the leak yourself.

I need a vacume diahgram fer a 97 chev blazer v 6 4 wheel drive. My ac is blowing out the defrosters and non of the other controls are workin

It sounds like vacuum is not getting to the vent, heat and A/C controls. Find the vacuum can. It may be under the hood on one of the inner fenders. The "one-way" check valve is usually located in the line and close to the can, make sure it works properly. The valve could be the very thing that's causing the problem. Trace the lines back to the vacuum block at the intake manifold or fire-wall, and also back to where the line goes thru the fire-wall. Check the can for leaks or obvious holes. They used to be just a plain metal can, but it could be a plastic ball. Check the lines as you go, for breaks and rub-thru's. Move the controls thru all settings and listen for vent door movement. Worst case is a bad vacuum motor or air flow position selector switch, and/or a faulty Blend Door Actuator. If you have been driving around with the Temperature knob or control set at the same spot for months, move it from fully cold to fully hot several times and wait for the air temperature to change each time. This will help reset the blend door and vacuum control system. Hope this helps... Let me know what you find.

Why would no air blow out of the dash vents but blow out of the defrost vents. The air conditioning when turned on does the same thing.

There's (flap or doors) that open and close depending where you are the air to come from. The door opening for the vents is most likely broke and staying closed or it is not getting vacuum to the door to open it. They charge $250+ to get into the air unit find problem and fix it. It it a very aggravating job for a person new to this. Take a swing by a air cond specialist to see if they can give you a better answer with the price and problem.

Air only blows out defroster vents

check the a/c doors, they may have jam, also if the system is non electric, check the vacuum line that runs to the a/c

i suspect the vents are controlled by vacuum and are not opening due to a vacuum leak.
