In order to get to the resistor pack you must remove the hvac unit from the car in order to remove the hvac unit you must disassemble the ac lines in order to disassemble the ac lines you must evacuate the system.Why do you need to evac the a/c system when doing this job? I am planning on doing this job soon and plan to bypass the resistor pack and have full speed only. My car finally failed VA inspection for no defrost. I never knew they checked that.
Thanks for the info. I was thinking that I would have to remove the clam and then drive my car to get the AC evacuated with clam off. For some reason I thought the refill of AC was done in the engine compartment and the drain was under the clam. Thanks for clearing this up.In order to get to the resistor pack you must remove the hvac unit from the car in order to remove the hvac unit you must disassemble the ac lines in order to disassemble the ac lines you must evacuate the system.
Take it to any trusty ac automotive repair shop and have them evacuate the system. The connections are in the engine bay on the right side of the car behind the passenger seat area. Have them evacuate the system.
[/QUOTE]The ratcheting crimpers are the the best, but but the price can be a bit high (I just found one on line for $200). But for normal home use you can also get by with a GOOD pair of professional crimpers. I have an old Klein hand crimper, but you can find them at any most any Home Depot or Lowe's. Klein makes professional tools for electricians, so they have them in the electrical tool section.
The Klein crimpers are pretty much a big pair of pliers that allow you to put a lot of leverage into the crimp. The crimp is wide and has the "peg" on once side that dents in the connector to make the secure connection. They really work very well, and they cost around $20. Admittedly not as good as one of the ratcheting crimpers (I have them for electronic connector - old RS-232 pins - so I do know how much better they are), but they do a more than sufficient job.
I the "old days", I used the typical hand crimpers - you know the kind; they crimp, strip, and cut bolts to length. They never did a good job, distorting the crimped connector, and often times having the wire pull out. Not so with the Klein crimper.
Here are two photos of Klein crimpers and a third of a ratcheting crimper. The first is the good kind that I've been talking about. The second is the typical type of crimper that most people try to use - the ones that don't work very well at all. (Note that the photos are not to scale - the first one is bigger and much more heavy duty than the multi-purpose tool in the middle.) The third photo is a generic ratcheting crimper - sells for around $20 (note that it squeezes the crimp but doesn't "dent" it).
Got the 134a evacuated today by a local shop and will be attempting the direct wiring of the blower to switch this weekend bypassing the resistors.Sorry, in order to access the blower motor/resistor pack, many pipes and components need to be dissembled, hence evacuation is needed.
It turned out good. I'd say it took me 20 total hours but I went very slowly. Look at my post at the end of this thread on what I did and for some pictures.Just curious how this turned out for you, mine s**t the bed on me today.
I tend to remove the "cheap plastic sleeve" and crimp the "raw" metal onto the wires. But before I crimp, I slip on the shrink sleeve tubing. Then when crimped, I cover the crimp with the shrink sleeve and heat up the sleeving - sealing up the joint.I've bought some before that have a cheap plastic sleeve that seem to "break" when I crimp them and slide off easily... is there any brand you order online or do you have a shop nearby that you get them from (home depot, autozone, etc). I tend to pick them up wherever I happen to be at... whether it be walmart or autozone
mouser has a substitute part available:Anyone know where to get the three resistors other than Mouser Electronics?
They are out of stock on the:
I don't mind paying a few extra bucks, but the kit is $150 on "some sites"
