my heater blower worked intermittently for about 2 weeks and now died.
What are some common causes, I friend told me to try the resistor block
and fusible links. I found the resistor block, but no luck finding the
link. Any help would be greatly appreciated.

Intermmittent to fail is usually a bad connection in the res block. Also do
a key-on tug test on all heater wiring, see if it starts.

With the key off, remove the resistor block, reattach the connector with
the block lying on something non-metallic, non flammable.

While heater blower SHOULD be running, with a pair of long-nose pliers
short across each component leg, esp the one that looks like a small
condenser.. it is the hi-temp cutout.

If you cant make it run that way, it's probably in the switch, motor or
fuse.

A very common occurance on these cars is that the motor starts to draw a bit too
much current and, over time, the connections at the motor or resistor overheat and
lose their tension.

Ok i couldn't get a resisitor block over the weekend so after testing
the blower on a bench (it worked) I replaced the relay under the hood.
The blower worked for about 1 hour and is done again. I would say the
resistor block is bad and blowing out the relay, or am I assuming too
much? Also the blower seemed to get slower before dying out.

Thanks
