1998 Buick park ave., what is that noisy thing under dash that runs with heater and ac?

Answers from the Automotive Experts

Amy Mattinat, Owner and Author at Auto Craftsmen Ltd Daniel, To answer this question, you need to bring your Park Ave. to an auto technician and let them hear "that noisy thing under the dash". It would be hard to diagnose your problem without the vehicle in front of them.

Amanda J. Pierce, MBA Daniel, You may be hearing the blower motor, sometimes a plastic blade can become dry rot and break off which throws it off balance. You may hear the "card in the bike spoke" sound. You could also have paper or a simple leaf that is stuck in the HVAC system.

Barb Petrey, President - DBK Enterprises Inc at Jiffy Lube It could be the gates that run it or the fan. Take it to a mechanic

Bogi Lateiner, Owner and Technician at 180 Degrees Automotive Hi Daniel - It depends on what kind of noise you are hearing! You could be hearing the normal noise of the blower motor or possibly (and most likely) the noise of a blower motor that is starting to fail or possibly hitting against something as it spins. If what you are hearing sounds like water gurgling, you may be low on coolant and you are hearing it as it travels through the system. You might be hearing one of the blend doors (the flaps that control where air is directed) sticking or binding. If it is a noise that is new, concerns you and/or is getting worse or louder - I*d bring it in to a reputable repair shop to let them listen to it. Hope that helps!

Laurie Sarno, Co-Owner at Super Girls Auto Hello Daniel it sounds like your fan motor needs to be replaced- hope this helps thanks Super Girls Auto.

Suzanne Grego, Technician at City of Philadelphia Fleet Management Daniel, I'm not sure if you just have a loud fan or if there is something else going on. I suggest you bring your vehicle to a qualified technician and have them listen to the noise. They will be able to tell you if it is normal or if further diagnosis is necessary. Suzanne
