WHERE IS THE AIR CON RESISTOR BLOCK LOCATED ON A JAGUAR XJ 2004 LOCATED?

I take help from online websites that have this service like helping in repair some like reliable-store have instant help.. others are a bit slow which I don't prefer... rest is up to u.. U can also get free manuals

Not being a smart Alec but the same place every car has them. Yours should have a plastic engine cover that you have to remove first. The plugs will then be visible in the standard locations on the cylinder heads.

check your blower connection.

Check the fan relay.

Check you fuse block

I can tell you upfront you must check your variable valve timing solenoids..codes p1396 and 1384 as for code po197/198 thats your engine oil temp sensor.po102 check your mass air flow meter connection right behind the air filter housing where the air duct elbow is located.The sensor could be bad.p0112 intake air temp sensor code.ok the p1224 is the throttle postion control sensor.make sure your battery is good...seems like these codes are related to low voltage also...but 1st make sure your fix that oil leak.

unusual for only one corner to be out, the common problems are, air leaks, between valve block and suspension unit, ride level sensors, normally the clamp on the suspension corrodes and allows the sensor to float,it sounds like a air leak on that corner to me. you can buy a leak detection spray to help find the leak. the pump is also troublesome. located front bumper liner lh, but that would affect the whole system, I would check the plastic pipe is ok from the valve block to the suspension unit first, then get the fault codes out of the air suspension module, the valve block is in the boot spare wheel well. hope this helps.

Intake manifold.

maybe the front is alright and the rear are the problem.

If your bonnet will not release, there is a rubber plug inside fender located up in
the wheel well under the latch. Remove the plug, stick a screwdriver up and pry the latch
back. The hood / bonnet will open.

First, check your fuse panel and see if you have a blown fuse. Replacing it will resolve the issue.

If not, fold down back seat and pull the emergency cable located near the key hole.

check the fan speed resister block... located under the dash in the duct work near the fan. i may have failed
