Default Heater Problems 90 Camry

The heater in my 1990 Camry only works about 1/3 of the time. Sometimes it
works perfectly and then sometimes it feels like im running the AC (the Ac
works great btw) does anyone know what the problem would be?

When was the last time you flushed/filled the cooling system?
If it hasn't been for a while, I would take it to a decent garage/mechanic
that has a REAL power flush machine and blow it out. You've probably got
gunk 'circulating' in the cooling system and blocking the heater core
(this is just a guess, BTW, based on 'experience'...)

A partly plugged heater core can cause driver shivers at very cold
outside air temps yet seem to work OK at more moderate temps. Or could
be one of the climate system doors not working or a bad heater control
valve. Have someone flush the coolant system including the heater
core, then go from there.

Check the diverter valve on the firewall infront of the driver in the
engine compartment, be sure it moves completely. A good power cooling
system flush is in order, and be sure to use distilled water

I had an 89 Camry, simalar problem, my Toyota service
manager (the Dealership owners son) said the cause was
likely the resistor element on the temperature slider lever.
He suggested sliding the heat control all the way to hot and
then back slightly to use a different part of the resistor
element, OR he could order a new part for near $300 bucks. I
chose the less costly option and it worked for more than a
couple of years. He told me the heater control is almost all
electronic, this was an LE with the push button controls.

You aren't near Greenfield, are you (course, I'm sure Jim wasn't the only
owner's son who ran a service dept...but he sure was one of the BEST!)
