Take it back immediately to who ever did the exhaust work.
The problem is that the rear heat/ac vent that mixes the two to control the climate is broken, I had it replaced at the dealership since it kept knocking when I tried to operate the rear climate controls.

It is common to have a knocking or clunking noise of a 99 Nissan Altima, even after the struts have been replaced. This may be due to worn ball joints. It is best to replace the ball joints, too.
the knocking is a broken piston rod or piston ring broke it will be from $550-$1k to have it replaced. u need to have it checked out ASAP
It is being replaced from underneath.
a place where water is replaced
the battery on your meter has to be replaced.
Could be the timing is a little fast.
I had the same problem when I cleaned and replaced my KN filter after 3 months of use. It was caused by too much oil on the filter element. It fowls the knocking sensor on the engine and causes the knocking noise at idle. I removed the filter and cleaned it. Then I very lightly oiled it and replaced it. The knocking went away in about a week. If it doesn't, you might have to replace the sensor. I'm not a mechanic... this is all the help I can give you. Good luck!
you re rear axle i just replaced mine it probably the front pinion bearing
A "knocking" noise sounds like a bad connecting rod bearing. You may be ready to "sling a rod". These engines are famous for it.
wheel bearings?
There could be a bad relay switch. The fuse that goes to these particular lights may also need replaced as well.
