Fix you HVAC blower fan module for less

Recommended Posts

I recently purchased 2 of these (had a minimum quantity required at the time) and they work great in place of our original modules. They do not have as many electrical contacts as the original, but 3 of the original contacts were never used. I paid $30.00 each a couple of weeks ago. They are now $12.00 + 4.39 shipping. This is the cheapest way I know of to get a “NEW” (rebuilt) module. I am working on a how to repair/replace the module (w/pictures), but will need a little more time to finish. The parts come from Asia and shipping takes a couple of weeks. Not sure if all year Reatta have the same module. This worked for a 1991.

Ronnie: Speaking as someone who has lived and worked in Silicon Valley for nearly 30 years, while design and engineering may be done here, the fact is that most electronics is actually manufactured overseas. Sorry, but we in the U.S. have priced ourselves out of the market. Especially here in California. Unfortunately, our politicians have been making things worse, not better.

In our 20+ year old Reattas, many of the electronic parts were made overseas. Look at any circuit board. Even if the board was assembled here, many/most of the individual components were sourced overseas.

Both Ronnie and Walt have valid points here. I would add however, that the trend of counterfeit (substandard or outright defective) semiconductors has become a major problem, as bogus parts are being supplied even through well known and respected vendors; often unknowingly. This has been going on for years, and has only gotten worse as the counterfeit operators (mostly of Chinese origin) have gotten more advanced they have been making knock-offs of more expensive/less common parts.

This has been a known issue in the electronic service industry for a long time now, and my other hobby - collecting and repairing vintage audio equipment - has been adversely affected by it as many high end power transistors turn out to be fakes that self destruct instantly on power up. On an amp with 4,8 or even 12 power transistors per channel this can be an expensive screw job, and a hard lesson to learn since many of these TO-3 output devices can sell for $20 each.

These Sanken/Sanyo "brick" type devices are also heavily counterfeited now, and it is very difficult to tell a legit part from a real one, as the package and markings are duplicated masterfully by those running the scam.

I cannot say the part linked to be the OP is bogus or not, but be very cautious about these things, especially if dealing with an international seller. The best protection I have found is to find a Motorola (or ON Semiconductor as it is now known) part that will directly cross, and buy that. If no such part exists, then you place your bets and take your chances.

Sorry, was not looking to open a can of worms. Bogus or not, as stated in my post, I have used them and they work. Lesson learned. In the future I will keep what I know and what I have learned to myself. A tutorial on how to R/R is dead. No offence taken Ronnie.

The sad part is not that the Chinese have filled a void, rather it is that we are losing our capacity to produce. Oh well, the politicos are fixing that, pretty soon the value of a dollar will drop so low that we cannot afford to import.

In the meantime we have to use what we can get to keep our cars running, with complex electronics that hasn't been used for twenty years, this is non-trivial.

Thank you, Brian, for sharing that.

ps I also Buy American when possible but even when "Made in America" often the parts are sourced to the lowest bidder. If I were repairing high power audio, I'd have to "power test" at 120% for an hour or two just to eliminate the defects before assembly. Some do but adds labor cost. It is a gamble either way.

bwarren-

I didn't intend to torpedo your worthwhile effort at repairing these modules, and would still like to see you do a write up on this repair if you are so willing. The purpose of my prior post was to caution anyone doing component level repairs that they need to perform due diligence on the provenance of any semiconductors they are buying to do so. Believe me, I am going through this problem myself in trying to source legit parts for repair of various electronic equipment, and have been burned a couple of time already by expertly packaged fakes that were visually indiscernible from their properly made counterparts.

So, if my rather verbose warning on the subject was construed as criticism, please accept my apologies as that was not my intent. Just trying to give a heads up to anyone doing these type of repairs that they need to be very careful about sourcing parts now.

bwarren,

Following Kevin's lead I not only apologize for my harshly worded post, but I have deleted my post. It was not my intention to discourage you or anyone else from trying to find new sources of replacement parts for the Reatta. My comments were a knee jerk reaction to seeing the Chinese part with the name Delco on it promoting it as a genuine Delco part. I shouldn't have hijacked your thread by posting my feeling about it.

Nothing like shooting the messenger.

Just goes to prove no good turn will go unpunished.

Keep the faith Brian. :o
