A/C Relay Location

In the case of my faulty CCV, high side pressure was slightly low but low side was clearly too high (it should be 20-35 psi or so). This is consistent with what you are seeing. Your low side pressure is even higher than what I was seeing but this could be explained by your higher ambient temperature or it could be that your CCV is simply in worse shape.

 

Does your rear A/C work? There are two expansion valves with the 4-zone climate control, one for front and one for the rear. I would expect that both expansion valves would have to be blocked to cause what you are seeing. Considering the damage that the lines sustained, I guess this isn't out of the question. The front expansion valve is underneath the passenger's side wiper. It's fairly easy to replace. I tried replacing the expansion valve first when I was diagnosing the problem with my car. It wasn't the problem.

 

I think a faulty CCV is a reasonable guess in your case but it could really be anything considering the fact that the valves were so badly mangled and debris could be anywhere within the system. Good luck!

Thanks Brett. 

I replied in the other thread, but in case anyone reads this both evaporator don't work so this points to a common fault, so thanks to Brett's previous posts from his experience, I have ordered the compressor control valve. Unfortunately the seller still hasn't been in contact and I've run out of patience, tonight I will pick up one from a shop I found here in dubai after some sweaty searching this morning. It's blatantly Chinese copy part but at this point I need a solution so worth the risk. 

I will be trying to get paypal to refund the other one which didn't arrive. 

I will update hopefully tomorrow with the results.
