05 X no heat

[raustinf16]

The Wifeys EX suddenly stopped producing heat. Fans all work well A/C works. I reset the computer. Me thinks it is an actuator. anyone agree or disagree? Where is that sucker located?

check the heater control valve under the hood. it is vacuum operated and wont work if the vacuum line falls off like mine did.

Thiis is an old post I realize but had similar problem with our X. No heat front or rear in Utah in December. Chilly ride. Fix was vehicle had run low on antifreeze probably from hot summer to cold winter. Filled overflow plus some, and immediately started getting heat in both front and back. Could be unrelated flook but it fixed mine hopefully it helps.

Make sure you have enough coolant/Water in your system.

Let the truck run at Idle for 20-30 minutes with the reservoir cap off and see what it does.

Had a no heat issue and this fixed it. Its a free thing so no point in not trying.

or your head gaskets are blown again... like mine.

2nd the blown headgasket, mine as well, additional coolant did help get some heat going.
