When heater is turned on!!!!!

Hi there,

I have a Buick Regal Coupe Limited from 1989.

When i turn the heat on, or the airco i hear a loud from under the hood.

Is this the waterpomp????

What can i do???

Many thanks and best regards from Holland

chances are the noise is either the blower motor that is making noise, or the AC compressor. If it was the water pump, you would hear the noise whenever the engine is running.

Thanks for your reply.

I have tested a few things. When i turn the heater on i dont hear noise. When i put the airco on it makes noise, a ratteling noise pretty loud....
So i think its the airco pomp.

And another problem. When i drive backwards and i brake, i hear a squicking noise. Is that the brakes...


btw

Nice one there on the pics....
