I've got a leak in one my rear a/c lines. I would like to fix this issue. However, I've discovered through some of the threads that this can be a pricey repair. I've been exploring short term solutions and I wanted to get some opinions. Has anybody tried by-passing the rear a/c? In particular, I've seen a rear a/c block kit in my research online. I'm seeking opinions on if this is a viable option from individuals who have a/c repair experience.
