Why does my front vents not blow air on my 87 cutlass?
There's a baffle (like a small door) that shifts and determines where air comes out of certain vents when you select floor, top vents, or a mix of the two. That baffle mechanism can get stuck on older cars. It's located under the dashboard and is not easy to get to if you're not familiar with disassembling your dashboard. If may just need some lubricant to get it to move freely again, or it may have a broken spring or 'arm' that moves the little door. Hard to say until it's disassembled. You can try fixing it yourself, otherwise find a local mechanic with AC expertise.
Thank You Very much I will get this fixed, much appreciated.
I have one last question. the vent that changes the direction of flow is it moved by vacuum line, cable connection or electric on my 87 cutlass.
For that model year it is likely moved by a vacuum line.
Were can I purchase vacuum line as the originals?
Any auto parts chain should carry vacuum lines. It's best to bring a sample so they can match it. Be advised the problem may be with the vacuum module, but the least cost option is to start with checking the vacuum lines themselves. On an older model car, they can eventually split open or crack.
Is the vacuum model the controller by the radio that turns everything? Cold to hot and etc.
