Does the heater blower motor have to have a gasket on it when I put it back.
Thank you for writing in. I cannot find a diagram or any proof of a gasket between the blower motor and its mount. If there was a gasket when you took it off, or if there is damage to the mount that would require a gasket for a better seal, you will want to try and find a replacement. Otherwise you should be fine without one. Good luck!
