It is hard to tell at night. I did see three hoses in that area right above where the air conditioning pipe runs into the fire wall. I can't tell the condition yet, but are replaceable with standard vacuum hosing or are they special parts that I need to order?

Why would the system fail only occasionally? Before the repairs the same thing happened, but then everything worked fine the following day. Is there some way to test it to see if it is at those elbows? Also, the condenser was replaced over a week and a half ago, and there were no issues until yesterday.

It was working all day yesterday. (I did get my oil changed at the dealer, but it still worked after that). The only difference is that I did several short trips to restaurant and then to the store. It stopped working when I left the store. It has started up the following day in the past. I will try it this morning to see if it starts up again.

Replaced the two outer elbows (the dealer did not have one with the small diameter in the middle). They said the old ones looked OK. I can here the vacuum system when I first start the car. The vents work OK for about 30 seconds and then they shut down. I did it twice and it did the same thing.
