2006 cadillac srx Heat doesnt get hot on drivers side. Is this controllled by a fuse?

ok, zero heat, but only on passenger side.
Caddy SRX
both passenger floor mode and dash vents all dead. blow but not hot.
does AC on, cold blow cold there?
front fails but not rear?
hummmmmmmmm
a complex system here, air delivery
but the SM says scan it first see if you have DTC errors?
check fuses.

me first guess is mode damper actuator failures.
and lots of tests like this in the SM

1. Place the mode switch in the PANEL position.
2. Observe the drive shaft of the mode actuator.
3. Place the defrost switch in the ON position.

Does the drive shaft of the mode actuator rotate?
etc, lots of tests in the service manual, to find dead vents or lack of heat or cold.

More then likely the temp. blend door actuator is bad , Videos on youtube showing how to test an replace . The video shows better then we could explain on here . Only other option would be to buy a service repair manual .

DTC B1340 Air Mix Door #1 Movement Problem !
The heater and A/C programmer supplies voltage to an internal motor that drives the air mix door. The heater and A/C programmer monitors the air mix door position feedback from a sensor on the motor. If the air mix door is requested to move but the feedback voltage does not change, the heater and A/C programmer will store DTC B1340. If the air mix door feedback indicates that the feedback is near the hot or the cold extreme, the DTC will not set. Evaluate the operation of the air mix door through self diagnostics as described in the test description.
Test Description
Perform the Diagnostic System Check before continuing with the diagnosis of this DTC.
A Scan Tool allows for the direct control of the air mix door by observing the following conditions:
• The air mix door position feedback value
• The value`s difference from the air mix door commanded position value
These readings indicate a fault internal to the heater and A/C programmer in the air mix door sensor feedback.

Did you perform the Diagnostic System Check?

With the engine running, connect a Scan Tool .
Turn the dual zone to OFF (passenger temperature offset at 0 or OFF).
Exercise the suspect actuator using the temperature control on the control assembly.
Is the door being commanded (COM) to the proper high and low values?
COM High 100 %
COM Low 0 %
Go to Step 3
Go to Step 4

If you are unfamilier with this , i suggest you take it to a ASE certified repair shop or the dealer .

Hi Amber,
I presume that you want to change the oil on the Cadillac. The link below will tell you how to change the oil, where the drain plug is and where the filler is a. It will tell you where the dipstick is.

sounds like it could have air lock in cooling system bleed air from system

Your spark plugs are located on the top side of the engine, if you follow down the spark plug wires it will take you right to them. You will have to unplug the spark plug wire to get to them.

clean ac drain hose whit a long screwdriver it's at the passenger firewall under car

Check the ballast for the HID bulb, it is separate from the bulb.

it is on the passenger side of the pan, if you cannot find it, you are probably looking at the trans pan, the oil pan will not look like a normal pan, it will be square and aluminum with all kinds of diamond looking deep etches in it.
