lol, if someone like you who knows all about these little beast's cant be sure, im not sure if i want to risk it! haha!
would toyota themselves know? or just try and fob me off and make me go for the most expensive :S
I've never replaced the matrix in either a UK EP91 or a Glanza V so I can't confirm from experience.
The EPC gives the following part numbers for a 01/1996-07/1999 UK EP91:
87107-10330
87107-42060 (substituted part number)
87107-10350 (for LHD EP91)
What causes some confusion are the part numbers it gives for a 01/1996-07/1999 Glanza V:
87107-10330
87107-42060 (substituted part number)
That would suggest that the UK and JDM EP91 use the same matrix, however the EPC also lists another part number for the matrix in a Glanza V:
87107-10340 Under model description it has:
±Ø (ØÔ Ë*À* Àþ ,Ä)
I'm not sure what
±Ø (ØÔ Ë*À* Àþ ,Ä) means, ±Ø in the description usually relates to a factory option so maybe it's the difference between manual heater controls and electronic climate control??
If your V has manual heater controls then I would expect a UK EP91 matrix to fit without any issues.
