I have worked and worked on this climate control til I am blue in the face.

History;

When purchases, found bad vacuum line on check valve, replaced. worked fine. 2 days later blowing hot air out the defrost all the time. Fan won't work, climate control computer seems to be dead.

action taken:
replaced the fan motor, climate control computer and fan speed selector. Still hot air out of the defrost all the time but now I have fan. Still no climate control computer working.
Replaced all four vacuum actuators. Now have fan, and AC everything seems to be working. Two days later back to blowing hot air out the defrost and no fan at all.
Pull the middle dash back out and found a mounting bracket for the lower actuator that controls the blend air flaps broken off.

Currently have no fan and the bracket is broken off the mount. Now I have to figure out a way to attach the mount back without permantly affixing the actuator to it where I can't get it off later.

Sorry, just had to vent. Any ideas why the fan stopped working AGAIN?
