Re: heater fan shuts off now and then?

["tmpintnl" <tobyp@xxxx>]

I believe that the common cause for this is a weak circuit breaker. 
The breaker trips after some time in operation, and then resets itself 
for the next cycle. If I recall correctly, there is an upgrade to a 
higher rated breaker that still provides protection to the circuit, 
but has enough capacity to allow the fan to operate for an extended 
period of time. The upgraded breakers use "loop-style" connectors, 
whereas the OEM breakers have a spade connector. This means that you 
have to change the connector ends on the wires to make them compatible 
with the new breakers. The spade style connectors are more prone to 
heat buildup and higher resistance than the loop connectors. There 
are two breakers, one for fan speeds 1 and 2, and the other for 3 and 
4. The breakers are against the forward wall of the relay compartment 
to the left of the fuse box (if memory serves). Unless somebody else 
on the list has quick access to part numbers, I will update later this 
evening.
