Factory HVAC Fan Speed: 4 speed
what radio you originally had? I bought used with aftermarket radio. I believe it had the 5 inch RA2 with VR button and mics in headliner. I have the puck roof antenna NOT the fin one.
It came with the manual turn knob HVAC controls.
I put in a 2017 Ram RA4 with nav PN#

I do have a Backup camera.
What parts I have bought are the radio VP4 NA 68270661AG
U-CNVHRNS-47SPD carplaynav radio harness
P68268186AA control module on the passenger side of the dash.
1UJ96DX9AC HVAC controller in the dash.
7 speed blower motor resistor
7 speed blower motor harness from a friend who got it from infotainment.com
My problem is everything works except the AC clutch does not engage. If I put everything back to what came in the truck the AC kicks on. I did change the pin 7 on the gray plug on the passenger kick panel and spliced into the 17 pin for HVAC control.
What am I doing incorrectly or what am I missing? I have 7 speeds from the fan, temp changes from cold to hot. It's just not engaging the ac clutch. I do not have power on either side of F62 fuse.
Any help would be greatly appreciated!
