When I have blower control on HI both blowers run full speed.
When I select a lower speed setting, the right motor adjusts accordingly but the left motor stays on high speed.
I have R&R the left blower motor, separated the housing from the motor, cleaned the relay with contact cleaner and cleaned the internal components but the issue still exists.
I have noted that the relay for the left blower tends to get hotter than the one for the right motor but cant think of any reason for this. I did note a hairline crack running from one of the left relays ports to another port and, with that in mind, I swapped the entire fuse panel with another vehicles panel and the high speed only mode still exists with the left fan motor.
Questions;

  1. Would swapping the fan motor with a donors fan motor make a difference?
  2. Is this a HEVAC control issue?
  3. Thoughts or suggestions as to troubleshooting this?

It's the speed controller on the blower itself, the bit with two big power transistors on it. One of them has gone short circuit. You can replace the transistors or swap the speed controller from another blower (or just swap the whole blower).

Dang!! Gilbert! Ya beat me to it!....Do you ever sleep?
+1 on the speed controller circuit. I replaced the RH blower on mine 2 days ago. Same issue. 20 bucks from the wrecking yard for a blower
and all is well.
I was going to see if I can find an equivalent replacement transistor and re build the controller.
Seems to me there was a thread about this on the dark side....now sadly not worth the effort to search the quagmire.

Cheers for that....
Anyone have a spare speed controller they would be interested in selling?
Finding a breakers yard in the Great State of Conneticut is like finding an ashtray on a bicycle. I found one on eBay for $69 but in the interim will hold off for a few days to see if someone here would have one that would be sure to be in working order on arrival.

I've got a blower that I took out of mine as the bearing was noisy. I only kept it in case anyone needed the speed controller bit.....

Sleep?? It's only 7pm here......

Ahhhh...... Sleep......As far as forums go, my brains are still set to Hawaii time.....even after not posting from there for 5 years now. (12 hour time diff.)
It just seems you are always on line either here or there.....no matter if I was in Calif, Oz or Hawaii.
On another note, Is it just me, or has .net become P-38 Kindergarten lately?
Between "RichardG" and Escape, you ARE the forum!.........Good job!

Back to topic: I will grab a few speed controllers when I see them. Lots of pick your own type wreckers nearby!

I usually check the forums in the morning (to delete the Russian spam), and when there's nothing worth watching on TV in the evenings (which is most of the time). So it might look like I'm always here but I do have a few hours off every so often.

Yes, .net is filling up with newbies asking the same stupid questions and the odd know-it-all who need bringing down a peg or two every so often. As even RRTH hasn't put in an appearance since the revamp, someone has to slap them around a bit.

I'm bunging a speed controller in the post for James in the morning but they are always useful to have a spare.

I went thru something similar with mine a year or two ago. New motor assembly is too expensive and I had to got through a few used ones before I found a good speed control board.

Next time, I’m taking a gamble with one of these:

New. Possibly OEM Valeo brand, and way cheaper than a new motor assembly. All of the used blower motors I have work great, the bit speed control boards seem to go wonky after a bit...

Aloha Gene,
Thanks for the link, but $78.50?? Robbery!

As I was looking, I found these:

Dirt cheap!
I cannot even find a pair of transistors for 9 bucks!
Will try one soon!
Thanks!

I just purchased and installed the controller as described in the link by BOLT on Sept 19th above.
Took all of 30 minutes to change out. Fixed the left blower motor issue.
I would say it was the best $10 I have ever spent but that would not do justice to the time I spent in Bangkok some years ago....
