Bmw X5 blowing hot air on one side and cold on other

[@guayo42]

FYI... this usually fixes the issue. I initially had no heat, changed the HCV and got heat. Summer came along and I had a mix of hot/cold air. Thought it would be faulty HCV, swapped it out and same issue. Checked coolant and pressures were good. Had to take to a shop, ran ISTA and multiple tests, no errors. Checked blend doors actuators and had to remove dashboard. Finally decided to swap out JBE module just to see what would happen, A/C was now fixed. I post this just in case someone is having the same problem after swapping out HCV.

Mine does that and did replace this part in the video because it was leaking coolant

[@guayo42]

@@robertmanning2581 There were two issues. The HCV was stuck and therefore I got no heat. Fixed that issue and then I couldn't get cold air. After troubleshooting, taking apart the dash, running ISTA+ diagnostic. No issues found. Shop decided to swap JBE modules and the A/C worked. The JBE was faulty even though it passed all ISTA diagnostics. No coolant leaks.
Two Issues:
1. HCV
2. JBE Module

Thank you for your video. I have a 2016 BMW X5 and no air is coming out of the vents. All I hear is air behind the dash, what can it be?

[@Frenko1]

Any chance you can make a video and email to me so I can see what's going on. [e-mail]
