Customer Question

There is a 4.5 amp draw on the battery. I have pulled, one at a time every fuse in all 4 fuse panels and still the draw is there. I removed the hfl module 3 years ago so that isnt it. I disconnected the positive connection to the primary fuse panel and the draw goes away.
JA: Have you checked the manual yet? Most vehicles have two fuse panels.
Customer: Did you read my post?
JA: What is the model/year of your Acura?
Customer: 2007 Acura MDX.
JA: Are you fixing your ZDX yourself? What have you tried so far?
Customer: Don't know what a ZDX is, what I have tried so far is contained in my first post.
JA: Anything else you want the mechanic to know before I connect you?
Customer: No.

In the primary fuse box are some black relays. The most likely reason for your battery drain may be the relay for the air conditioning compressor clutch. These relays have been know to stick and cause battery to go dead. I would pull the relay out and see if your draw goes away.

if you can not figure out which one if the compressor just pull them one at a time until the draw goes away.

I already did that, the draw stays. The a/c relay is in the secondary fuse box.

Please don't bill me beyond the $5.00, I don't think you're canned answers will help. Thanks anyway.
