2001 lincoln LS V8 Code # 1299

It sounds like the bleed procedure is pretty close to accurate. I think I've posted the steps on here, but maybe I only sent an e-mail with the steps (since it does include photos). That is odd though that you don't get the steady flow of coolant. When you had the car running for an hour with the car running you had no signs of engine overheating? The water pump and thermostat must be working in that case....

The next quick test would be to feel the DCCV inlet and outlet hoses to determine if they are getting hot. If the inlet is hot and neither of the outlets are hot, even with the DCCV electrical connector unplugged, that would be a pretty good sign the DCCV is a problem. Psuguy131 recently posted how to identify which hose is what.

As far as the sensors, you can access those from the driver's and passenger's footwells. You need to remove a few trim and/or duct pieces to comfortable get to them. I'm not sure if you can even see them with the center console trim removed.

I woke up frustrated today determined to find the cause, i blead the system 3 times and the heat got warmer, even on high, driver side still colder than passanger. I am doing this with the DCCV Disconneted...is that going to cause me a problem? but it is good enough for now (if im not toasting something leaving the dccv always open)

P.S. Still not hot

I don't expect you'd damage anything by leaving the DCCV disconnected. It probably will trigger a code in the DATC system though.

The funny thing is there isn't a code in the DATC...seems to work to a degree.

I'm not getting a 1299, but this thread seems to be about heater issues so...

2002 Lincoln LS V8. The drivers side air outlets are discharging air at the proper temp but the passenger side seems to be full hot. My wife is also getting a little hot about the whole situation. Once in a while the problem goes away, but it always comes back.

Also, last summer, the AC would go full hot on occasion but replacing the DCCV had appeared to solve that problem. Now I'm wondering if they aren't manifestations of the same problem.

I have replaced the DCCV, the DATC, purged the AC and re-charged, and then replaced the passenger side temperature sensor. According to what I read in the shop manual, that is everything that could cause the problem.

Does anyone have any ideas of where to go next? The frustration level is getting pretty high.

What does a DCCV look like.

Off the vehicle it looks like this:

See post number 3 here for instructions on pulling the DATC codes.
