Electrical problems - Page 2

I too suspect loom damage, but work gets in the way of finding out much between weekends.

In addition, as both heated rear screen and heater blower are not working, changing the relays over would prove nothing, so I must sort through my big bag of realys for a similar known good item to see if it is simply a set of unconnected faults presenting the proverbial basket of red herrings.

After reading more on the site (my wife will kill me soon, she says she is a car widow) I have found that the rear blind sticks in some cases, no doubt especially if some idiot like me keeps punching the button like I did.

I will keep reporting back as ay answers might be helpful to other owners.

Best wishes, Frank B

Frank its common for the radio not to be coded. Many were upgraded by the dealers and they often didn't bother to activate the code. Mine is the same.

"checked plenums no sign of water damage on the ECU and he checked the BCU for water ingress". (in his post) Chris ...

If a connection to a lamp is intermitant, then the IPK will flag it up as a blown lamp. Does it say which actual lamp? Make a note of it and check the lamp connections and socket for the lamp.

Sorry to butt in this blog but you say you have the new super dooper unit in your car did you get it off of Radioguy if so any pointers of how it fits example is it easy.

The basics are easy, but it depends on your car model and year how easy the rest might be. It took quite a bit of experimentation to get everything spot on, so most of the potential issues are now resolved for most people.

The one outstanding issue seems to be if the car is fitted with a twin radio antenna system, where reception can be a problem.

Thanks to Mike Noc for his post on the radio coding.

The more I find out about these cars, the more I realise how little I know in relation to the vast pool of knowledge of the rest of you guys - long may you drive!

I have not has a chance this week to look at the car, but I need to sort the heater blower at least as the misting up is getting chronic in the colder weather.

I have resolved to check the earths, as rover apparently used to switch the negative, or 0V of things like the relays.

I looked for a change of state on the heater blower relay with a meter (DVM) and could detect none.

The 12v feeds were both there, so a switching problem must be occuring.

If it was all through hardware switches it would be easier to check, but our wonderful control systems get in the way of that.

Best regards, Frank B

Frank,

You've probably already found out that the ATC system uses electronic blower control and not the traditional resistor pack. A member recently had a fault with his and successfully repaired it.

I think that was me. I never actually finished the repair - too busy with other things, I simply swapped it out for another module.
