Ac/Heat help?

Recently my truck is only blowing heat or air conditioning on full blast in my 2012 Toyota Tacoma.

Level 1, 2, or 3 blow exactly the same which is almost nothing, then if I switch it to 4 it is full power.

I just don't know what exactly I will need to look into and fix.

Any input is very helpful.

Thanks.

 

Sounds like you need a fan switch resistor. Pretty common and a cheap fix. Look up fan switch resistor. You should find lots of info.

 

Autozone has one for 52.99 shipped. It's Duralast brand. Should I go with a different brand you think?

 

Rockauto, same part half the price. The Airtex is the same as Duralast minus a rebranded box and some serious markup.

Check your plug to see if it's burnt firat... https://www.tacomaworld.com/threads/blower-motor-plug.230055/

I had to replace mine a few years back andthe resistor was actually fine. There are a couple threads on here about it.

Good luck!
