Have to had any of these problems

I took it to the local dealer and they said that the pump was 240 and I would also have to replace the booster which was another hundred and thirty and then also the master cylinder according to the service bulletin I got on parts.com and found the vacuum pump for a $110 i tested booster and it operating normal dealer also said vacuum pump was on back order for 3 mths...but this is not a common problem....yea right...so yes 43000 dollars on truck i purchased brand new ill be doing it myself last month my ac compressor went out that was $1500 and has been in and out of shop since i bought it...never again will i buy a gm product sad thing is on 50,034 miles on truck

It is not producing enough vacuum at idle

This happend to me today first my ac compressor shells now this i reported this i urge everyone to report this it was so sudden if i was pulling a trailer i would have most likely wrecked
