82 celica supra Where can I source one of these??? Or does anyone know ther workaround for this problem. I am truely stuck. This is the 5-prong pigtailed resistor. the fifth wire is for the automatic climate control. Baring any fis can I rewire a 87138-14061 to work the three speeds knowing the climate control won't work?

Does anyone have the resistor values? I may have to rebuild this myself.

I going to suggest bypassing the resistor altogether,but then you would ON(full) or OFF.
Maybe Kevin Kisseberth or Bob Shapton can dig one up. Maybe Supkar.
Rich 64N.
I'll guess that the resistors are VERY low ohms,but at least 10 watts.
Dr. Jim? Ray 85p?

If it was me I'd look at the Mk3 version and make an adapter plug for it. Looks really similar in construction and size.

I haven't had any problems with mine, so I've never looked into a substitute.

Some are "sand block" construction, while others are open coils of Nichrome wire, which is hard to solder to.

My understanding is that the fifth wire is necessary for the Auto Climate Control to work. I actually found one by emaailing everyone that was parting out MK2 parts.

Hi Lar1949

Are you sure that it's the blower motor resistor?

http://www.celicasupra.com/forums/showthread.php?8899-Know-anything-about-this-part
This link talks about what happens when it fails. There is a pretty good description of how it works with the automatic mode enabled.


This is apparently a picture of what this resistor assembly looks like. The bare wires are in the air stream of the blower motor to keep it cool and prevent it from overheating and going open circuit. if the blower motor dies, these overheat and get taken out as well. Junk such as leaves that get in the air plenum can damage them too.

This link indicates that the nichrome wire will be hard to solder so just beware.

Unfortunately, Dave A in the above link hasn't been on this forum for several years. If I have an opportunity I will ohm out the resistors. This wire is probably from something like a clothes dryer heater.

Good luck,

Dale

Nichrome wire is readily available from on-line sources. It's sold by either diameter or resistance per foot. It's usually crimped to the connections, or spot-welded, but it can be soldered with acid-type flux. *IF* you solder it, make sure yo clean ALL the flux residue off with hot water, as the stuff will continue to be acidic after it's been heated.

And don't breathe the fumes as you solder it.

Still think you should look at the Mk3 piece. The resistance specs between the two are pretty close and it has the correct number of pins. Its also available new as well from Toyota and aftermarket. Since the Mk2 one has a pigtail you could make an adapter harness from that and a Mk3 parts car. MX73 ones have 2 bolt holes similar to the Mk2 as well.

I tend to agree. Unless it's a "numbers matching" type of restoration, there's no reason not to substitute a part with better availability.

I share your frustration. I have a1983 with the same problem. I found a used resister pack on eBay and was assured it was tested . Unfortunately I have only medium and high speeds which is better than just high . Did you find any answers ?
