Update on Blower motor blowing on high only or not at all:
Decided to pull the blower motor after blower controller kept blowing the 30 AMP Tosihba transitor.
Yup, it was the blower motor, only 54,000 original miles, but the blower motor looked like it had thousands of miles more on it, pretty corroded and beginning to break down. Ran like a champ when hooked directly up to the battery and by passing the controller.....however it was drawing way to much current and not blowing the fuze.
Changed the transitor in the controller, then ordered the motor and new heater core from Europarts.com.........get this....a Syracuse, NY dealer quoted $75 per hour for labor for 6 to 8 hours, $236 for the blower motor ($57 at Europarts.com), $325 for the core ($97 at Europarts.com)., the transitor was ordered from MCM on the net for $10.40......total dealer quote From $1011 to $2011, my total cost $181 and five hours of time start to test drive....Quasimotors sight write up (Thanks Quasi) made it simple.
Some tips:
No need to remove any engine components. Remove only the false bulkhead.
Have a helper, it is neccessary to speed things up.....especially to hold the evaporator out of the way.
A long screw driver for a pry bar is handy. Need a long flat narrow metal object to reach in behind the evaporator to release the passenger side clip holding the blower unit in place, the drivers side is easy to get at......careful not to break the clips......the older cars will have brittle plastic so go slow and easy and you won't break stuff.
No need to remove the lower windshild screen if you are careful and your helpey helps to guide the blower unit in and out....care not to break the flap control arm going in and out.....
a little careful manuevering and patience and it will come out....the pry bar helps to avoid the wiring harnesses on the drivers side, the clips on the blower unit want to hang up there.
Don't be afraid to carefully kneel on the motor to get in there and get a good position over the unit while working it out.
Also the helper is a great assist in holding the evaporator unit up and over towards the passenger side of the car, it will move about six inches up and 3 inches over....very neccessary. Silicone really works great to secure insulation if loose.
Other than that Quasi's sight has it nailed, even for a novice mechanic like myself it was not as daunting as I thought....its just scary getting started, but hey the worse you can do is mess it up and take it to a dealer anyway....!!
If anyone wants suggestions, don't hesitate.....thanks to those who assisted me earlier with trouble shooting suggestions.
