    My vehicle will begin to over heat if the car is left to idly running, but as long a I am driving the vehicle the temperature doesn't increase, ( again unless it sits and is allowed to idle) someone had suggested that I have heater core flushed and another said to have the fan motors checked. what do you suggest. The heat in the inside stopped working first and then the blower on the heat stopped working , I attempted to check into getting it repaired, but became discouraged when it was stated it was a very complicated and possibly expensive task....But then I felt like an idiot when it was asked of me if I had checked the fuses, and how sometimes the fuse going out can affect the heat from working HELP ??????

Replace the relay , when a relay sticks like that , a good test is to slap it with something like the handle of a screw driver , see if it un-sticks , its not a fix , just a test . cheers'

Air/heater wont shut off


If the blower motor won't shut off, pull the blower motor relay in under hood fuse box. That should kill it till you find the problem. I don't know if you have automatic hvac or manual hvac?
Can you check for hvac trouble codes? Some of the national brand auto stores will check codes for free.
If blower motor wiring connector has both voltage and ground, it will run as long as the battery has voltage.
I saw two different wiring diagrams on your blower motor, I don't know which one applies?

Hvac blower will not shut off, even when vehicle is shut off and key is out of the ignition


Hi, the likely problem is a shorted blower relay. Unfortunately, your relay is integrated into the motor/resistor assembly, so you would need to replace the whole thing to fix it. You can disable the blower high setting by pulling out the IGN3 fuse under the hood, but I'm not sure the car will run without that fuse. At least you wouldn't have to disconnect the battery to keep it from draining. Please let me know if you would like procedures to replace the blower motor assembly, and thanks for using FixYa.

Where the relays ac of a 1995 cadillac deville is locate the blower of the a/c dosen't stop when i turn off the a/c


Hello. Will do my best to help, You have this listed as a 1998 DeVille, in the verbage you say its a 1995. okay if the blower motor continues to run when you turn the key off then regardless of the year model the electronics in the blower motor has failed and it will have to be replaced. If its running with the key off you can disconnect it under the hood. It is located just off center to the driver side. It has a 3 wire connector this will keep the battery from going dead. Hope this helps. Thanks

AC stop blowing 2004 Cadillac Deville, is there a relay or fuse to check before I have to look at the blower


Check the current with a test light at the blower motor.
If it is not getting current, then the fuse or relay is bad.
Check fuses first, as this is the cheapest fix.

Trying to access maxifuses/relay center


The fuses for the blower motor and HVAC module are in the rear fuse/relay block located under the back seat.

To remove the back seat,simply grab the front of the seat with both hands underneath and pull straight upwards, this releases the spring clips, no bolts or screws to remove.

I have a 2006 Grand vitara and the A/C or Heater does not blow air. What part is responisble for this.


FIRST CHECK HVAC FUSE AND BLOWER MOTOR FUSE AND RELAY.IF BOTH CHECK OUT OKAY PROBLEM COULD BE HVAC CONTROL SWITCH OR MODULE OR THE BLOWER MOTOR IS BAD.TO KEEP FROM SPENDING ALOT OF MONEY.THE HVAC CONTROL MODULE CONTROL SWITCH VERY EXPENSIVE.IT COULD COST $300.00 TO $400.00 DOLLARS.WHAT I WOULD DO IS REMOVE BLOWER MOTOR IN THE LEFT REAR TRIM PANEL.HOT WIRE TO BATTERY USING JUMPER WIRES.IF BLOWER MOTOR RUNS ITS THE HVAC SWITCH.IF BLOWER MOTOR DONT RUN REPLACE IT.IF THE HVAC IS BAD BEST FOR DEALERSHIP TO CHECK IT OUT.BECAUSE YOUR DASH HAS AIR BAGS IN IT. WHICH WOULD BE DANGEROUS.

88 cadillac deville, ac blower fan wont shut off, even when car is turned off and key removed. I tried disconnecting the battery to reset the system but it still runs when battery reconnected. Also, car...


Ralph,
Most common cause of this is the blower fan (proper name for the fan you refer to) continuing to run is a shorted out Electronic Climate Control Module. This solid state device replaces the older style fan speed resistor block (at about 4 times the price) This unit is found on the top of the HVAC box under the hood. (HVAC means heating, ventilation and air conditioning) The HVAC box is found on the passenger side of the firewall. Look behind the A/C's accumulator. It will have an electrical wiring plug on top of it. It will be fastened to the HVAC box with a few 7mm hex head screws. Very easy to change.
FYI, do yourself a favor and replace the blower fan motor at the same time. The Electronic Climate Control Module usually fails because the motor is drawing to many amps of current. This is because it's bushings are worn out or the brushes are worn out.
This is very common on Cadillacs and Buicks.
Charlie
PS Not sure why car won't start. Either you drained the battery or blew a fuse which controls starting the engine. Need more info regarding the "no start" condition.
