!971 blower fan replacement with A/C installed


rockyard

Recommended Posts

Hello,

Just got myself a 1971 2002 in pretty good shape however the blower motor was frozen. I have managed to loosen it but it will not run on it's own, in truth it is still pretty snug.

Can anyone point me to a "How To" to replace the blower motor with dealer installed A/C (Looks like the AC guts will be right in the way) Or better yet anyone had any luck unfreezing a blower motor while it is still installed.

Thanks, [/i]

do you have a Frigiking or Behr A/C unit? I've done both and will be glad to share some tricks. I did a column years ago on pulling the heater with a Frigiking unit, and have also done a Behr unit.

Since all A/Cs were dealer installed, the trick is to have enough slack in the A/C hoses between the compressor and the evaporator unit inside the car so that you can remove the outer housing and then slide the evaporator unit over partially into the passenger's footwell...that'll give you enough room to weasel the heater box out into the driver's footwell. Depending on how much slack you have, you might have to do it backwards (A/C into pax footwell, heater into driver's). You'll have to remove the clips that hold the hose along the right inner fender well and firewall to get the slack.

Drop me an e-mail and let me know which unit you have and I'll send you some instructions...

I scored a used fan motor @ the u pull it for my fridgeking. The price was real cheap and they had three 2002's to choose from. and two had A/C systems so i had my pick.

Under the FAQ section on this site, under body & interior, there is a write up on

heater box refurbishing, if you have to remove the motor, you have to pull the heater box, drill out the rivets, replace with small screws & nuts & washers, just to get to the motor. Might as well do it right & follow that faq as a guide.

If you can get a stuck motor to go again while it is still in the car, it would only be if your lucky, You need to get some WD-40 into the bearings of the motor, which are just brass bushings on both ends, you can kinda get to one on to top or outside, but the other is not so easy to get to with the heater box in the car.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
