Air

Well, I need help...

My wife's 1993 Buick Skylark in a shade of blue, has one more problem to deal with. When you start the air conditioner, even though its cool air it only dribbles out.. Even with the dial pointing to Max -- we get more air from our 1 year old who puffs up her cheeks and spits out tiny bits of air...

I really do not know where to begin... Is this a do it yourself job..

Any pointers to resolve this issue would be nice, since 90 degree weather is approaching.

My 1st guess would be a bad blower motor resistor.

I would agree with Cheese, except it depends.

Does the fan SOUND like it's getting up to full speed and just not coming out where you want it? Or it the fan always running low speed, no matter where you put the fan switch?

Need more description of the problem.

(1) it sounds like it has the speed but just not much air coming through.


(2) If it was a blower, is that hard to fix?

Did you check to see if more air is coming out a different vent?
If so it could be a misaligned blend door.
I was just wondering because you said fan had speed.
If not I would take Cheese's advice and check the resistor.

I agree with Bill.

On many GM's there is a vacuum wheel at the back of the A/C controller. That goes bad and the air comes out everywhere but where it should

It's an 8 dollar part on some GM vehicles.

That being said, it's a scorcher in NYC today and the A/C in the 84 Olds was really comfy. Way to go Autofrost. lol. In there since 1997 .

The air does not seem to be coming out any were else minus the little bit through the vents...

Where and what is the blower resistor --- is that hard top replace?

It's usually on the firewall by the accumulator.

common problem

Sounds like your evaporator is leaking.

When refrigerant escapes from an a/c system, oil escapes with it. This oil covers the evaporator fins. The fins soon become clogged with airborne debris, which restricts airflow.

This is a common problem on many GM cars with evaporators manufactured before April 1994.

You can usually inspect the evaporator by removing the blower motor resistor and peeking inside the evaporator housing with a flashlight. If the evap is leaking, you'll see oil & debris on the evap. fins.

I never seen a blower resistor, nor an evaporator.. Are there any distinguishing characteristics that woul pin point the right part?

Are these parts hard to work on?
Are they costly, if replacements are needed?

You should get a repair manual for your vehicle to at least familiarize yourself with the components.

As stated earlier, take a look at the links in my signature file below.

If not, get a repair manual, or ask for the exploded view of your A/C components from the dealer's parts information.
