SOURCE: location of blower motor relay

better late than never....
The blower relay is one of two identical relays next to the clutch pedal above the fuse panel. I just had to replace mine (1996 Protege DX). I switched the two relays and now the blower works fine. Not sure what the other relay was for... but the car doesn't seem to miss it yet! The relays have H270 panted on the side of the black plastic covers. You have to pull down hard to get the relay off the clip it is fastened to, then unplug the four prong connector. Good luck finding one. The books all call for a 6 prong relay. I am going to find one in a junk yard rather than calling Mazda. I hope this helps... I searched all over the internet and couldn't find any answers so I figured I better post mine here...

I have a 2007 HHR, my temp gauge stops working and the same time the a/c stops blowing cold air...I called myself checking fuses and a relay, can you help?

You mean the blower motor stops blowing air , the A/C compressor is still engaged ? The temp gauge shouldn't have anything to do with the blower motor .But stranger things have happened on these systems when they are controlled by a electronic module (BCM )
Circuit/System Description
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The ECM sends the temperature data via high speed GMLAN serial data to the body control module (BCM). The BCM then sends the information via low speed GMLAN to the IPC in order to display the engine temperature.
The BCM applies voltage to the blower motor through the HVAC relay. The resistors and the blower motor are in a series circuit. The following list represents the number of resistors in series with the blower motor per particular speed request:
• Low speed--4 resistors
• Medium 1 speed--3 resistors
• Medium 2 speed--2 resistors
When the operator requests High speed, the HVAC control assembly applies ground directly to the blower motor through the high blower motor control circuit.
Do you know anything about automotive serial data communications ? GMLAN Is general motors version of C.A.N controller area network .

How to Diagnose Controller Area Network CAN

Do you know anything about diagnosing automotive electronics ? Using a digital volt ohm meter ? Using wiring diagrams to pin point locations in a electrical circuit for testing ? Do you know what a factory componet location diagram is ? It takes more then looking at fuse's an relays , to see if current is flowing in a electrical circuit .

Electric Testing Techniques You Need to Know

ECM Inputs and Outputs Diagnosis Free wiring diagrams ! Enter vehicle info. Year , make , model and engine size ! Under system click on HVAC , under subsystem HVAC Controls . Then click the search button , then click the first blue link . This is the blower motor control diagram . Do you know how to read a wiring diagram ?

2006 ford falcon engine warning light on and K Mart auto said fault code P1479, primary hi/low speed fan primary circuit fault?

ford code p 1479 refers to engine coolant blower motor , high blower speed ---circuit malfunction===causes --wiring--engine coolant motor relay
if you have fitted an after market radio and this code since appeared , it is most likely that you have taken power for the radio from an inappropriate source that is depriving the relay of power and that has revealed the fault code
if the fault was showing before the radio was fitted , then replace the relay

Blower motor works on high only in my 1994 Cadillac STS.

Sounds like either the blower motor switch or the motor resistor has failed.

What does the fault code 0483 mean for a 2005 dodge ram 3500?

computer confused by cooling fan voltage/current level. Is the fan working? If yes, may have a short. If no, try hotwiring to battery to see if it's good. If fan works by hotwire, suspect relay is bad. Check all wiring before buying any parts. Relay does not click in until engine is hot. Let me know if you have more questions.

P0483 Engine coolant blower motor, rationality check -malfunction
Causes: Wiring, engine coolant blower motor, ECM

My chevy beretta has no heat and i want to find a diagram of the fuse panel but i cant find one can anyone help me?

Is there air blowing out the vents? If not then you most likely have a bad blower motor relay. The relays are in you fuse box in the engine bay. Switch the horn and blower motor relay and see if the blower motor works then. If so they you have a bad relay. They can be picked up at any auto parts store.

If you have air blowing but its not hot then you have a cooling system issue. Check to make sure your coolant is full in the radiator and the overflow. Also make sure the car isn't overheating. Could be a bad thermostat, water pump, radiator or low on coolant. If low on coolant check for leaks.

Good Luck,

Engine temperature peugeot 307 sw hdi 90 rapier

behind front grill (near engine coolant blower motor) you have two relays for engine blower motor and resistor. Or one of this relay is foulty (or wires in conector) (oxidation becouse of the wather), or the resistor is broken. yours engine have two speed (stage) fan and probably first does not work. you can check when engaging AC first stage should work instantly. second start in about 100°C
