Heater AC motor, relay change

[Thomas C Potter]

Does the coolant hose need to come off??? or is there enough slop in the box once the relay is loose???

If your changing the BCM, it can be done without taking off the hoses.... it's easier done with the hose(s) off.

If you take the hose(s) off you'll have to burp the system.
