Hello and welcome to justanswer.com,
Let's see if we can figure out your a/c issue in your MDX.
first according to the schematic the relay receives power from two sources. Fuse #3 (7.5 amp) from the driver's fuse panel and fuse #59 (7.5 amp) from the under hood relay box. I am assuming you have checked both fuses and they are ok. if there is no power at the fuses, then you will have to back probe the respective fuse panels to see if there is power into the panel. you may have a faulty fuse panel causing your issue.
I'm getting no voltage at the MG Clutch fuse in the under hood box.
So, no power at the fuse or relay.
Ok, got it.
It appears that the other fuses are ok.
#3 in the cabin has power.
#59 does not.
The connections appear to be ok, no signs of corrosion or broken wires.
excuse me, but i don't understand why you rated my service poor. First i believe we weren't done with the diagnostics on your issue. second i believe i had helped you greatly explaining the circuits and providing you with several diagrams of the circuits.
If you left the negative feedback by a mistake please withdraw the rating, if you are not completely satisfied then understand I believe WE WERE NOT finished working on a solution. I do not deserve the rating you have given me so far. Not finding a quick or guaranteed solution to your issue is not grounds for a poor rating. Problems especially electrical issues are difficult even with the car in front of you, imagine what it is like trying to fix it on the computer.
Sorry about that, I don't know how that happened.
I think it happened when viewing the message on my phone.
I'm trying to figure out how to retract the rating...
You have provided excellent service and I haven't had time to verify the power at the connectors.
It's difficult to take the connectors apart, and I need to coordinate the time for when I don't need to use the vehicle.
OK thanks for your response. if you have any problems retracting the rating, please contact customer service and they can help.
the connectors can be tricky yes, but take your time. whenever you get a chance to test the connections that will be fine, just post your findings on the thread.
you can accept this answer with a excellent rating and it will erase the negative rating. thanks again and i will hear from you soon.
It's been a while, however I've now figured out that I have power getting to the clutch relay. When I jumper the relay, the AC clutch does not engage.
