The problem I am continuing to have with my 91T is the evaporator freezing at highway speeds. Below 60mph it cools great. Above that, it's lousy. I may also have an air leak problem. I haven't had time to really investigate this since the last time I replaced the Xvalve. The anti frost switch is a probe that sticks into the evaporator. Look on top of the evaporator box. That little box with the 2 wires is the control for the switch. The wires go from that switch to an electrical connector on the right (passenger) side of the box. I haven't gotten into the switch yet, but I probably will before the end of the summer because the freezing is driving me nuts. Do you ever get hit in the face with ice chips? That doesn't help my mood.
Yes, the bulb needs to be insulated, but not the valve itself. The bulb attaches to the evaporator outlet tube and should be covered. I bought this rubber insulating tape in the HVAC section at Home Depot called Rubbertex or something like that. I haven't used it for that, but I think It would work. YOu could also use the felt weather stripping and some duct tape.
I am off for the weekend. Send me an email for further clarification next week.
