Hi,
Internal fridge in armrest just started to heat instead cooling. Is it driven by A/C compressor?
Looks like compressor doesn’t start either when I’m switching AC. Any idea what to start looking from?
Thanks.

Hi,

I had the same problem. I was able to locate the problem, it was a frozen pipe from the cooling unit (88501E).

I'm not sure for this part list, might be a different Toyota. But it showes the pipes going to and from the cooling unit. One of them was broken :(

Happy new year :)

Thank you. This pipe in fridge compartment?
It looks like compressor is not even running when I switch it on AC. May it be because of low outside temperature?

I can't seem to get my AC compressor to kick on either when its very cold outside. I thought setting it to MAX would allow it to kick on but no results for me.

Also, I didn't know the 100 series has an option for a cooler box in the middle. Wish I had that.
 
Can you measure the refrigerant pressure? You just need a gauge. If not, could you maybe park your truck in a heated garage, let it warm up, and then see if the A/C is actually working in the cabin? If not, that might suggest there is a leak and you lost the refrigerant. (Happened to us.)

In my 80 series, the fridge was always the first to go when I started having A/C problems (a small leak that would necessitate a new gasket and a system recharge, for instance). It would heat up because of it's proximity to the transmission tunnel and because there was a small fan inside to circulate the air. If the compressor isn't kicking on, I'd find your local A/C specialist; it's probably a issue with the overall system more than the cooler itself.

No, one of the pipes below the base plate broke next to a fitting / sleeve. Also this parts list is from a Toyota, but I don't know exactly which Toyota, year of manufacture, etc. Should only serve as an illustration.

Good point. In my garage is constant +7C now. I think I have to wait for warmer days.
