the heater and blower fan have stopped working

[modelageek]

The blower motor began to work intermittantly. Now almost never. Of course checked fuses, took out the motor checked operation, took out resistor checked for corrosion and for continuity. all good. at times, there is no power to the blower. When it works rarely, it works at different speeds.

hoping for the relay to be sticking but cannot find it on a 94 model

I looked the part up for you on Rockauto.com. it appears it might be part of the blower control switch. I would pull that out and clean/check it. I could not find a separate blower relay for a 94 but they do have a separate blower relay for a 96. and i know my 99 has a separate one in the distribution box

I had a 91 Navajo do this to me. Every time it happened would go out and wiggle the wiring connection and it would work just fine again. Check your connections next time it happens.
