Air Conditioning problem

2015 crewmax limited. AC doesn’t seem as cold.

Had a 4Runner that had to have the evaporator replaced which requires pulling the dash. It also had a sight glass you could see bubbles in to see there was a leak in the system.

Is there a sight glass on the tundra?

 

With the use of 134A since 1995 the sight glass has been mostly phased out due to air bubbles being present in 134A making the sight glass unreliable. You are immediately jumping to worst case thinking evaporator which is very unlikely since were only talking 7 years. If it's just not blowing AS cold then you have a very small leak somewhere. The biggest issue here is finding a place you can actually trust as every garage now has a simple machine that does everything at once. It will evacuate thus pulling a vacuum and then set a timer to check if there is a leak somewhere. Hopefully it will be someplace simple like one of the two schrader valves and once the fix is complete the same machine will charge the system and your good to go. AGAIN, finding someone who won't lie about what is leaking is your biggest issue. One piece of advice to everyone is running your a/c in the winter a few times to keep the o-rings and everything else lubricated. Most leaks are from seals drying out. If you live in real winter areas your defrost will take care of that.

 

One of the first checks that should be done is one you can easily do yourself if you haven’t already. Your cab air filter. A dirty, plugged filter will cause low duct airflow and drastically reduce A/C performance.

 

I’ll check the cabin filter but I feel like I changed it not long ago.

also I live in south Florida so AC gets used 365

 

Cabin filter looks good but I’ll replace it anyway. Guess I’m going to have to take it in and see what comes of it
