blower question 1988 300TE

[krjt]

88 300 TE.

Couple of days ago, I noticed that my blower was not blowing like a hurricane when defrost was engaged. the blower was at one speed without any increase no matter which button I used.

A day later, my blower is inop. nothing being pushed at all. I looked at the fuse and it appears good. should my assumption be the blower motor going off? or is there a test of the control panel? I assume that it is the motor because pressing the different fan buttons should give me some fan activity. Is there a resistor I can check?

Should this be a fan, what brand is preferred?

Thanks.

just tested the fuse and with motor on, the fuse gets 14V on both ends of the fuse.

If one of the dash board buttons was bad, the others should still work. I am now assuming that the motor or the resistor is bad. Correct?

Thanks.

i will try to weigh in here the best I can.... i had a motor which seemed to be hanging up a bit.... i think it fried the resistor.... i pulled the motor and it was not turning like it should when i put 12 volts to it..... i guess i gambled a bit...because i used some tranny fluid to help the blower bearings a bit..

i got a new resistor off of ebay i think.... less than 70 dollars if i remember... i also got a new blower motor and just have it one the shelf now..

no problems since... this was on the CE... i keep looking for resistors at the bone yard...but those are gone along with blowers.. i keep a lot of spare parts

i also have another controller...but i never bothered to check that....
