Q: Rumbling sound from the exhaust

asked by on

The AC in my vehicle no longer works. Also, I hear a constant rumbling from the exhaust that gets louder when I press the gas.

The AC could have a leaking compressor or condenser, and would need to be checked and tested for the failure. The exhaust rumbling may be the exhaust pipe rusted through. This is common on some of these cars, and would need to be looked at to see if the pipe can be repaired, or if it needs to be replaced. Sometimes, a similar problem happens to the muffler. I recommend that you have a mechanic, like the ones from YourMechanic, inspect the sound coming from your exhaust, in order to make a proper diagnosis.
