Blower motor- speeds lost. Resister pack fix.

[timsrv]

The problem seems to be the A/C cut relay. I can't find its location in the "Body Electrical" section of the manual, though.

I'm not entirely sure this relay is the cause of your problem, but it's behind the lower right corner of your glove box. Good luck. Tim

Thanks for the information, Tim - you are our greatest technical resource.

It turns out that the A/C cut relay was my problem - because it WASN'T THERE!! Neither were the two fuses, the blower relay, nor the circuit breaker! And the bracket where they're mounted was turned upside-down! Fortunately I've always made a point of salvaging electrical parts, so was able to put everything in its place. I think the two fuses are 15 amp.
That's the last time I let anyone who doesn't understand electricity replace my blower resistor...

[timsrv]

Ha Ha, not being there could certainly explain a lot. But that brings up the question of where these components went. Did this van not have a working fan from the day you purchased? These relays usually don't just get up and walk away . Glad you got it figured out . Tim

Yes, these 2 fuses are 15A. Are you saying a "mechanic" did this to your van ?

[Flounder]

When I first bought the van about 5 years ago, the two lowest speeds on the front cabin fan were not working. I knew right away what the problem was. But I wasn't driving the van much, and not at all during the winter. Last winter, just before leaving to go to work overseas, I put it into storage at a friend's place in central CA and asked him to replace the blower resistor; even showed him pictures of where it went. When I came back, ALL of the fans were inoperative. Just got around to troubleshooting a couple of weeks ago. I'm taking the van down to CA in a couple of weeks; will look for the missing parts then.
Thanks again for the assistance, Tim!

Figured I'd post in this thread since I just had to deal with this. I went ahead and just ordered the part off rock auto. Takes 5 minutes to swap out and I have the two low settings again so it's not full blast or nothing! Glad I stumbled upon this thread, I thought it would be more in-depth to fix haha.

I have a 1988 toyota 2wd cargo van. Since i bought the van 3 years ago the heat never has worked. Now i'm living in SLC where i NEED heat!! it's been a brutal winter thus far. As for the van, I found this forum and looked at the heater relay, and the breakers. both the front and back breakers seem fine. I pressed the buttons on them both (which isn't really a button that presses...?) and nothing. when i turn the heater from off to low it makes a click clack sound that is coming from the blower motor maybe. As i don't have an ohm meter i can't tell whether or not there is juice going to the blower motor. I think the blower motor is done and that the click clack sound is current trying to get it going, and it ends at the motor. I do not know though. Can anyone help? I replaced the relay for the heater, and still nothing. Also on the A/C circuit with the photo, there is 2 15amp fuses. In my van I am missing the right one, but not just the fuse, there is nothing inside this fuse housing. no wires leading to it. Now i don't imagine the breakers are bad, seeing as how they are super basic. and the relays are fine, i have extras, and i don't imagine these break very often either.

as well as the windshield wiper fluid... this is another thing. It did work at one point. Then I never felt the need to use it, so i didn't for a long time. Now I need it. It's not working. .When i press the button, the motor in the back kicks on, and shoots fluid out of the motor. not at first, but after about 4 seconds comes fluid flowing out. I wonder if somewhere in the hose, it's either frozen or pinched, causing a backup and then fluid to come out of the pump. Or is the pump faulty?

Any help would be appreciated! -sam

Remove your glove box, and then then the relay cluster behind it. The resistor pack is lower left of the blower motor in the air plenum, usually a white plug, 2 screws holding in the resistor pack. Pull it, inspect the coils on the back side, if they are broken it will be obvious and then there's your problem. Check your fuse cluster as well. Aftermarket resistor pack are available or maybe save a few bucks and get lucky at a wrecking yard. There is also a relay built into the fan speed switch.Check your fuses and resistor pack 1st.

[timsrv]

Here's a quote from earlier in this thread:

When you have a blower problem the 1st thing to do is check the breaker. There are 2 of these (one for the front blower and one for the back). Use a paper clip or something small to stick into the little black hole (see picture below). If the breaker is tripped, you should hear a metallic click and the fan should start working again. You should have your fan set on high to test just in case the resistor is burned out. If that doesn't work, then check for 12vdc at the blower motor leads. Don't use a common ground (put your meter leads directly on the wires going to the motor). Report back what you find and we'll continue on from there (if needed). Tim

Note: Having a blown resistor won't prevent fan operation on high.

[Fillupamerica]

alright i checked for voltage at the blower motor leads and there is nothing. There is voltage at the blower relay next to the a/c cut relay. also when i switch the fan from off to low I hear a click clack that is coming from the main heater relay just above the fuse box.

[edit] THERE IS VOLTAGE at the leads to the blower motor! so.... bad blowor then?
The resistor is toast as well. but should still work on high with a bad resistor.

[timsrv]

If the motor is receiving voltage, but not running, then it's toast. Here's a thread that should help you replace: http://www.toyotavantech.com/forum/s...rk-works-again

[Fillupamerica]

Thanks Tim. I'll repost when i replace it this weekend or next!! fun fun!

[Fillupamerica]

All right! Heck yeah! who's got heat rolling in their whip? This guy!!

an easier job than i though it'd be. but damn, how many screws are there in a regular dashboard? there had to have been about 20+ in this one. whew. that was fun.

Tim thanks for the help.

[sammylf]

Hey i recently purchased a Tarago 89 and its been fine but recently the fan stopped working completely. it did resume a few weeks later but no doesn't work again on any speeds. I can hear the relay pulling in but nothing happens. I can't find a fuse in the fuse box so wondered if there is one in another location?

Also my dash lights stopped working? is this a fuse or will the bulb need to be replaced??

Help would be much appreciated

Thanks

Where can I buy breakers, specifically the yellow top ones in the picture below, online? I tried a few auto parts stores and have shopped around online without any success. The power window one on mine has been completely blown.

Any recommendations?

Thank you!

I'm not sure what that's for.......sort of hard to tell anything from that picture. If you could get a close-up shot of the pin configuration and / or tell me how many wires and the colors of them I could probably figure it out. My guess is it's not related to the blower circuit, but who knows.

These things don't fail very often. Personally I'd grab a few extras from a salvage yard. I think it's likely you could still order these from Toyota (probably expensive though). Tim

Thanks Tim! I figured as much. Headed to Pick n Pull tomorrow to see if I can find anything. If not I found some $30 ones online.

[ReggieVanBusen]

Ok, so I found 30A breakers, but was trying to find a 20A breaker.

Could I use a 30A breaker instead or will it ruin the circuit?

Thank you in advance for the help!

[timsrv]

Breakers are there to protect the wires and should be rated slightly below max capability of wire (you want the breaker to blow before the wires melt down). If the circuit is rated for 20 and you're using a 30, you are living dangerously. It would be fine if there's never a malfunction, but things could get exciting (and expensive) if there's ever an overload. Tim

Well the blower motor has finally decided to retire after 30 plus years, I’ve been looking and reading thru the thread to find the location of the resistor pack on the van and also in the previa so I can pull those parts along with the blower motor.

Anyone have a photo of what it looks like and the location (van wagon/Previa) that would be a tremendously helpful. I think there’s a few Previas in the yard, if they look good and I have time I’ll pull all of them.

Thank you
