    Blower Motor

    How difficult is it to replace the blower in a 98 Deville (heat/air) I suppose thats what it is blower stopped and I could smell burned wires ? or insulation off wires..A chevy dealer wants $347.00 just for labor. The motor costs 250.00 fromparts store.

    Re: Blower Motor

    I had the same problem with my 95 Deville and it is fairly easy to change. I would first look at the plug and make sure it is okay and then test the BM. In my car the BM comes out in 3 parts and you do not have to move the engine. I removed all 5 of the bolts holding the BM to the case and then removed the 3 bolts on the motor itself. Once you do that you can pull it apart from the cage and it will come out in 3 pieces. I got mine out of a 98 with a Northstar so I am pretty sure they are the same as far as disassembly. The way I found to test the BM is to ground the black and grey wires and put 12v to the red, the motor takes a couple seconds to come on and will be on full blast so hang on to it. I hope this helps if I am wrong I am sure someone else with more experience will comment.

    I ordered the 4 seasons motor and my mechanic says he'll put it in for $105.00 says its a 1 1/2 hour job. Dont understand. Another mechanic says its 4.5 hour job because you have to lower the cradle and tilt engine forward plus the original motors were no good and Cadillac had to modify them and he had to redo some wiring. Almost every forum I go to said something about dropping the engine cradle slightly so you could tilt the back of the engine away a little from the firewall in order to clear the hvac motor. I've never seen such confusion over replacing a blower motor
    Thanks for the replys guys..As always I.ve learned a lot from this forum..

    GM has a long history of making it near impossible to replace blower motors. I am replacing one now on a 66 Impala and it requires removing the inner fender. Chalk another one up in their long line of poorly designed systems.

    Yes one of GM's wondeful ideas, let's make this our legacy impossible blower changes... can't remember what car I owned you had to cut hole in the inner fender to replace the blower. Ranks right up there with Cadillac putting headlight relay under carpet where it gets wet easily and craps out.

    It shouldn't be to hard to get it out. You might have to remove the brace between the strut towers to making getting at it easier. Definately not a 4.5hr job. Get your mechanic to do it if you're going to pay someone.

    Re: Blower Motor

    One other thing...In one of the Cadillac forums one guy said the 4 seasons motor looked just like the original but the original is 12 speed motor(???) and the 4 seasons is only 3 speeds. Any truth in this ?

    Was it a 98 Deville or are they all the same to take out and install ?

    Up to '99, they are all the same.

    Blower speeds are controlled by PWM. I don't think there are a set number of speeds.

    I changed my blower motor in 20 minutes at the wrecking yard doing it the way I described above. It is not a bad job at all once you figure out how the motor comes apart.

    Electric motors have no "speeds". It's not like there's a transmission.
