Land Rover Repair: Air Conditioning Disco 2003, oxygen sensors, best guess


Question
I've had a host of problems within the last month, none of which are related to my current issues - but I'll give a brief summary for background info.

1. Dealer just replaced Exhaust Manifold gasket - within 24 hours my check engine light came on

2. Returned to the dealer this week to have the light evaluated and had my front oxygen sensors replaced. The light is now gone, but within 10 minutes ....

3. ... My air conditioner completely stopped running. All of the displays work and I can hear it from the hood, but no air is blowing. Before it quit was sputtering and had shut off once or twice in the last two weeks, but always came back on. The air is cold, but was blowing very weak and when it was on the highest setting it was VERY loud.

4. My next concern in that it takes a while for my truck to get up to speed. It seems like the power just isn't there. Once I get up to 70 or so it is fine, but over 80 I feel a slight shake.

My goal is to get it in good enough working order so that I can trade it for something that is less of a headache - without paying an arm and a leg. I've already spent a pretty penny getting number 1 and 2 done.

Any ideas? Thanks in advance.

Answer
On the air conditioner my best guess is that the blower motor has failed, or the fuse is blown, or there's a wiring trouble.  Blower failures are fairly common here in New England.

As to the problem getting up to speed . . . if your dealer just changed oxygen sensors I would have thought they would have driven it and noted that.  What did they say?  If they have not already done so the next step would be to ask them to drive it and give their opinion.
