Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Under the hood at the blower relay, if you remove the relay and turn the key on are there 2 pins there which are showing battery voltage?
should I use a ground to the pins or go between the pins for the voltage
Use a chassis ground.
With a ground to the pins I have 2 with 12v
Turn the key on and command the blower on. Install and remove the relay, does it click in your finger tips each time?
chris no clicks when relay install (tried both old and replacement
u still there
The HVAC control provides the ground to the relay to energize the blower relay. So that means your HVAC control is to blame or this relay is bad.
