Thank You, I will check the vacuum lines then I will lube the valve before I go back to a repair shop. I will let you know the results.

I have a 96 960 with the trouble code po410. I had it checked and was told it was the secondary air system malfunction. They replaced the air pump and the check valve. I drove the car for approx. 50 miles and the same code came back. Need help on this repair. If I can repair this myself I rather do ...

I have a 1996 volvo 960, my a/c works but after driving with it on for about 20 mins. it would stop blowing cold air. I could turn it off or shut the car off for about 15 mins and it would work again for about 20-25 mins. Any feedback would be greatly appreciated.
