HVAC problem

[EVOKIN]

Anyone having problem with their hvac unit?

My hvac will not stay on when I turn it on. It shuts off about 5-15 seconds. Sometimes it will come on for 5-15 seconds when I'm driving if I kept it on. Now it will not come on at all whenever I tried to turn it on.

Any ideas? Where do I start to check for the problem(s)?

Anyone out there have any info on this??

So weird, there's another guy with the opposite problem that posted a couple days earlier. His won't turn off. Check the service manual (not sure of the link) but it's in the other post. :smash:

I've found the source of the problem and fixed it. It was the transistor by the blower.

I hope this help whoever have this problem with their HVAC.
