Subject: Radiator fan & A/C problem|
I've got a 2004 Dakota Quad, and it's developed two interesting (and related) issues:
1) the radiator fan NEVER comes on. if I'm idling at a light, the temp goes up, "Check Gages" light comes on, but fan never engages. when I start rolling again, engine temp goes down.
2) the air conditioner only cools if I'm moving--air blows out whenever the A/C fan is on, but the air isn't cold. BUT, when I start moving, the air cools down (to a VERY cold temp). This behavior is the same whether I start the truck and immediately drive or if I run for an hour or so and then stop at a stoplight--if I'm not moving, the AC isn't cooling.
I haven't done current testing on the fan, but my guess is that it's the electric fan, or maybe one of the relays/electricals, and since the fan's not running, the condenser sensors aren't detecting air flow and are inhibiting the compressor?
Anyone have an experience like this?
