My a/c switch, defroster and even the fan switch is all off and the fan still stayed on?? do you think it will be the temp' switch?? i just had it changed last year, after market parts though.
 
Thanks for your reply

Well there is the temperature switch, and 3 relays in the circuit.
 
Why did you replace the temperature switch last year? What symptoms were you having, and how did you determine the switch was bad?

Last year my Fan not working at all, the mechanix told me its the temp switch thats gone, so i had him flush the coolant and pop in a new temp switch and its working fine, it come on when the engine is heated. but now it stayed on always, i pull the connector plug to the fan now, so it would stop running, is it safe now, until i find a solution to fix it?? do u think its the temp' switch or the relay?? Thanks for ur advise.
 
Regards

With the engine cold, disconnect the wire to the temperature switch, verify that the radiator fan is still running. If the fan stops, then your temperature switch is bad.
 
Assuming the fan is stil running after pulling the wire to the temperature switch, then pull the Radiator Fan Relay #3.
 
If the fan doesn't turn off, the the problem is your Radiator Fan Relay #1. If the fan does go off when you pull Relay#3, let me know....as we'll have to figure out whether the problem is in Relay#2 or Relay#3.

pheww after digging 30cm of snow, this is what i found.
 
I pulled the wire to temp' swith not directly at the switch, but on top of the rad, there is another connector, connecting with the wire to the temp' switch. 2 wire in, 2 wire out.
The fan still run, i pulled Rad' Fan Relay # 3, fan still run, then pull Relay # 2, fan # 2 goes off, then pull Relay # 1, Fan # 1 goes off??
 
I tried the same with Dash fan turn off, defroster & A/C turn off, same result??
do you think there is a ground broken somewhere ??
 
Thanks you so much for your patient.

Check your relay #1, it appears to be defective.
 
The primary coil is on pins 1&2. 12V on pin #1, ground on pin#2.
 
The secondary switched contact points are on pins 3&4. With pin 2 grounded, apply 12volts to pin 1, and verify that contact points are working correctly.
 
Do not swap relay#1 with either of the other two relays. They are different.

i have a multimeter and i can check for continuity, but when u say pin 2 grounded, do i actually tied a wire to it and then the body of the engine to create a ground??
How do i apply 12V to pin 1 ?? sorry i am a newbie at this.
 
Thanks

Yes, connect a wire from pin2 to ground, either the negative post of the battery or any metal pice of the engine. Then apply a wire from the pin1 of the relay, and touch that wire to the positive post of the battery.
 
When you are doing that, you want the continuity meter (measuring ohms), to be measuring across 3 to 4. You should see the meter change from infinite resistance, to no resistance, to infinite resistance as you connect and disconnect the voltage on the primary.
 
I'm expecting you will find that your ohm meter never goes to infinite resistance across 3/4.

toyota camry just won't go..... on a clear and mild weather day the forward gears just seemed to just jump ship reving the engine seemed to give some push but realizing the catastrphy my daughter steered the car to a safe place and parked it out of the way. It is a 1996 toyota camry LE sedan, 99067 miles ,transmission never been rebuilt , the tranny seemed to stall occassionnly but with enough rev's would pic up and go....when I heard of this wile working construction in salt lake city Utah, I reccomended that she have the trans. flushed but to ofen repairmen would just shrugg and say they didn't want to risk further tranny problem and refused the work. Shure enough I hadn't been home long at all when she called on the side of the road sayin guess what...I'm in knox. tn. and my camry needs help...
Well I've got the fluid out the filter off as well as solinoid 1&2 and as I was taking off the rear sol. I noticed the bolt was about two threads loose whaat would cause this and more important do you think these would cause the tranny to shut down or is the speed sensor suspect to, also is there a way to bench check these to see if possibly the loose bolt was the problem...
Thanks so much for your help

Hi folks, 99 camry 4 cyl, 165,000 miles, I lost the intermitten feature on my wipers and they stop on windshield now as opposed to returning to the cowl. other than that they work fine. Should I start at the wiper motor or switch? also what kind of job am I looking at if it is a switch? I have had good luck as a do it yourselfer with some automotive education. Thanks Ryan
