My heater/A/C works intermittently. I have a rear heater/A/C (because it's a Van) and it continues to work no problem.

Check coolant level first it may be low. Then pull hvac fuse inside car with key on that resets actuators as the temp may be acting up.

Coolant is OK. If it is a fuse why would it work sometimes. For instance, yesterday it wasn't working and I drove over a bump and suddenly it started working.

If that is the case then there is a loose wire like a ground. Have a local mechanic look at it and make sure you tell him about the bump and then working. Pulling the hvac fuse with key on resets the actuators as I thought that may be the problem.
