Boxster Heater Not Heating Much..
Discussion
Hi all,
Over the weekend I've noticed my heater doesn't seem to be kicking out much heat. Temp was set at 22c which is usually as toasty as I want but whacking it up to 26c didn't get the car feeling like a sauna either. (Made no difference if the a/c was on or not).
Any ideas what might be up with it/what to check?
Cheers,
Steve

You should easily be able to melt your shoes with a Boxster heater 
You can get a lot of info on what the sensors think displayed on the display if you've got climate.. Don't worry, you won't break it, you're just reading the values.
First, press and hold the Recirculating Button, then press both Temperature Buttons (+ -). To enter the Diagnostics, you hold down the Recirculating and Air Up buttons simultaneously for 5 sec. The + - will then scroll up/down through a list of 'C' codes. Pressing the Center Vent Button will alternate between the 'C' code with it's actual value. To exit and return to normal operation, press the Auto Button. Here is a list of the available codes:
0c - ERL
1c - Oil Temp
2c - Inside Temp - From the Sensor mounted in the Aspirator Assembly at the side of the Dash
3c - Outside Temp - From the Sensor inside the Air Inlet of the A/C Unit
4c - Outside Temp - From the Sensor in Front Grill of the Radiator. Data is fed to the Climatronic from the Instrument Cluster. When not moving, the Instrument Cluster OBC Temp Display retains it's last setting until moving. This is to prevent heat emanating from the Radiator affecting the Temp Sensor. The Climatronic uses the lower of the two values in determining Fresh-Air Temp.
5c - Outside Temp - matches OBC outside temp display
6c - Coolant Temp
7c - Footwell Discharge Temp
8c - Sun Sensor (dash top)
9c - Sun Sensor
10c- Passenger Compartment Fan Speed
11c- Passenger Compartment Fan Voltage
12c- Temperature Mix Flap Command (1=COLD, 100= HOT)
13c- Temperature Mix Flap Position
14c - Central Flap Command
15c - Central Flap Position
16c - Footwell/Defrost Flap Command
17c - Footwell/Defrost Flap Position
18c - Recirculation Valve Command (1=OFF, 100=RECIRC)
19c - Recirculation Valve Position (feedback)
20c - Vehicle Speed in kph, updates once per second. This is True Speed, not the Speed+Safety Margin displayed by the Speedometer.
21c - Engine RPM in hundreds, also updates once per second
22c - ?
23c - ?
24c - Sun Sensor, Exterior Lights Switch, and Panel Lights control (term.
58 & 58d voltage) - used for A/C Panel Display Illumination
25c - ?
26c - ?
27c - ?
28c - Fan Speed
29c - ?
30c - Engine Run Time in seconds (255max.) (=0Xff)
31c - Timing Counter
32c - Displays Test
33c - Software Version (usually 3.4)
34c - ?
35c - Outside Temp from Inlet Sensor (filtered)
36c - Temp
