Interesting the different issues with these fans. The fan works fine, was bench tested before installing. I replaced the original fan with this one a couple years ago because of this issue. So its not the fan, I messed with controls last night. Pulled controls out sanddd the contacts, checked ground connections. At this point I still think its the contacts/circuit in the controls. I want to source another set of fresh air controls to try.

I've done my share as a mechanic. i may recheck that at some point but right now i want to test a different control unit because ive had 2 fan boxes installed and they both acted the same way - so my thought is to test a different controller/sliders one that tested fine in another vehicle- btw- i want to be put on the list for that A/C box, i was reading your thread on that and it seems like it might be a bit of work but worth it for those of us in the south! - there is another member that had put together a mount etc too i think and is using a newer a/c compressor that will draw much less drain on the motor- i just dont know about running the a/c lines etc. - any way i digress--- i need to test a different controller -- |
