2002 Nissan Altima Repair Question
Nissan Altima Knob Problem
2002 Nissan Altima 4 cyl Front Wheel Drive Automatic 110000 miles
My switch on the panel is stuck it does not go from cool to heat.
I had noticed it was sticking about half way but then I had to force it to the warm side and then he wouldnt go back to the cool side.
but when i turn the fan on it blows out cool air even though the thermostat is on the warm side.
not sure if because it is stuck which is causing me not to have heat or if the heating element is bad.
I am not technical / a mechanic, but here is a simple check, then the FIX is pretty easy and I have a SHORTCUT so you can get heat NOW for ZERO COST (less than 1 minute) below...
CHECK- the cable that is attached to temp control knob open / closes a temperature "gear" just above the accelerator... Look to make sure this black sheathed steel cable is attached to via a metal clamp and most importantly snapped onto the plastic "gear" to move forward back the round gear. Reattach or perform fix below.
I JUST replaced mine last week - below is what to do for the REAL FIX and/or a SHORTCUT to get heat NOW! The "knob" in the control panel attaches to a small steel cable in the back and the plastic clip in the back is most likely broken. (notorious design flaw).
You can easily replace the whole blower/temp control panel in about 20 -60 min, 10-15 screws, and < ~~$100 for a used control panel from a junkyard. You will need to remove center area of dash, find diagram on web, (or just pull platic piece down/off below a/c control - NO screws- PROMISE.. (the plastic piece just above the "secret compartment door" in front of gear shift area). Then undo single screw exposed on psgr side (by glove box) holding the center dash. The big center area then pulls straight out - NO more screws, Yep, just the one! Once this is, off take out radio 6-8 screws + electric clips+antenna, then the A/C heat control module 4 screws + electric clips. (it will still be connected to steel cable running down to temperature control "gear" just above accelerator. Look at the back of your middle "knob", chances are when you turn knob the cable doesn't move b/c not connected any longer. It is broke, get a new used module. Simply put in by reverse order... The steel cable is held by a metal click clamp and snapped on the "gear" below dash above accelerator... Be sure to Attach new one with knob and "gear" set for FULL heat / cold or you will get luke warm when knob is supposed to be on full heat.
** Make sure when getting new, that you get the steel cable detached from down by the accelerator area rather than trying to use your old cable and somehow clamp into the new plastic control module**
***SHORTCUT to heat NOW *** NO COST FIX! Less than 1 Minute-
You can bypass the knob and simply push the cable / gear yourself. You will need to be parked and get on floor just above the accelerator. There is a black sheathed steel cable held by a metal clamp and then snaps onto a plastic "gear". This cable pushes / pulls the gear to open close the amount of heat! simply push the gear forward / back. This is what the CONNECTED cable is supposed to do for you. Can't change while driving, but if you OPEN / CLOSE the control then you can regulate amont of heat with the amount of blower / windows etc. You will have full heat / cold!
**Be sure to use masking tape to mark the 4-5 electical wire clips you will disengage for reverse order of reassembly when removing radio and a/c controller**
good luck. let me know if you still have questions... I can add more details if you need / contact me.

I'm having the same issue..I need to set it to heat for the winter. I had my mechanic do it last year but he's unreachable now. For heat do I pull or push the cable? Could you give me step by step directions? Thank you so much, Marcie
