akacheesy 0 Posted December 8, 2016 So I just fired up the 'rado after my week away at work to find myself without wipers, front and rear, no blower, no heated rear screen. Checked all the fuses and all looks fine. Anyone had this issue? I'm thinking it could be a relay or something. Quote Share this post Link to post Share on other sites
seanl82 23 Posted December 8, 2016 Think there are additional fuses above the fusebox that attach via black holders. These iirc can cause these issues if blown. Quote Share this post Link to post Share on other sites
akacheesy 0 Posted December 8, 2016 yeah, I know but how does one test a relay? They all look fine to me. Is there a list of which ones do what somewhere? Quote Share this post Link to post Share on other sites
akacheesy 0 Posted December 9, 2016 Just in case anyone is reading this thread, I took out relay no 72, 99 & 18. Opened them up, sprayed them with contact cleaner and put them back, everything works fine now but really couldn't tell you which one was at fault. Fixed one problem and discovered another, rear no plate lights has a well dodgy connection, time to invest in a soldering iron, the joys of owning at 23 year old motor Quote Share this post Link to post Share on other sites
marks2 0 Posted December 9, 2016 (edited) 72 is the Rear Wiper Relay 99 is the Wash wipe Intermittent Relay 18 is the load Reduction Relay A number of these relays have PCB's that have electrolytic capacitors installed. These capacitors are getting to the end of their natural life cycle. I have replaced all mine (+ those in the Engine and ABS ECU) + Re-flowed a lot of bad solder joints. The mechanical coil / switch assembly is generally very reliable. If there is any interest I can build a guide with photos?

Wiring issues, structural / bodywork maintenance, etc. Not attractive propositions for a solid daily driver any more unless you like keeping busy with this kind of tinkering.

Whilst this is very true Jim there are preventative measures that can be taken so that your corrado is no less reliable than any 5 year old car. If the G60 I have just stripped for spares is anything to go by the issues are 2 fold; age and previous owners bodges. I've re-built my ABS / Engine ECU + relays and will start on the looms in the spring. Happy to build a quick how to guide; but only if there is sufficient interest?

Jim 1 Posted December 9, 2016 There is always interest in DIY guides, especially when it comes to rebuilds, etc! If you have the time to write something up, it'd be much appreciated. Quote Share this post Link to post Share on other sites
marks2 0 Posted December 9, 2016 Ok. I have a spare g60 engine / abs ecus so ill knock something up over the Christmas break. Quote Share this post Link to post Share on other sites
