Pontiac Problems? Ask a Mechanic for Answers ASAP
The noise is on any time the ignition switch is turned on even when car is not cranked or running. The noise sounds like a pencile hitting a piece of plastic every second. There may be a plastic door for switching the air flow to feet to front of dash to defrost. I will check to see if it comes out in all areas tonight.The air conditioner and heat still work. Could a vacuum be craeting this noise. What moving equipment is under the dash behind the gloove swing passenger compartment? Does it take an expert to remove the dash to check out?
You can call at(NNN) NNN-NNNN I can let you listen on my cell phone.
When I change the air flow to floor, front and defraust it comes out as it should. The ticking sound is like a clock. It makes 10 ticks in a row then skips a tick then makes 10 more in a row repeating the sequence. What is behind the dash that would make a noise like this? It is not under the hood. How much would it cost to repair? Would it hurt to run like this until I can come up with the money to repair. Do you know a vibe dealer that could quote this repair?
